I do not have addictions, but I am +1 on the importance of sleep-wake cycle, and I go to bed between 8-9PM on most nights. I also am a completely changed person in terms of punctuality - whereas before I would continually be running late, now I make it a point to be exactly on time. Before, I did not even know the pleasures of calling somebody exactly when it was agreed - if I said I would call at 4:30PM I would call at 4:30 and not at 4:29 or 4:31. Of course I make use of Google Calendar for it but Google Calendar does not call or go places for me - it just helps me with organization and reminders.
There is a lot to be said for reducing the number of decisions you make about mundane matters ("minimizing decision-making fatigue"), which in turn allows to focus on more important decisions and longer term planning, as well as on enjoying life in the moment without always thinking about choosing what your next step is. Some people, including content authors on the PsychCentral site, take it to an extreme and eat the same things over and over again - I take a middle ground and choose from a limited set of dishes I enjoy making and eating.
When I have time to make my bed, I feel so much better, and apparently there is research that explains why this is so.
I have a limited set of clothes which can be combined and mixed-and-matched.
I do laundry every other Saturday. I see my psychiatrist every other Saturday (on alternating Saturdays with laundry).
On Saturdays I cook enough soup to last a week.
Eggs for breakfast plus some variation in vegetables.
When I prepare next day's clothing the night before, next morning has less stress associated with it.
Spreadsheet with finances reconciled once a month, shortly after my American Express statement is posted and can be downloaded as a .CSV file.
Everything that can be purchased from Amazon purchased from Amazon, without comparison shopping. I do make some exceptions, but they are few. When I reconcile finances, I compare the AmEx statements against Amazon order list because they have been known to overcharge me and then I file a dispute via American Express.
Making sure you put "money" in different "bank accounts" - I have learned it from somebody. You need to read books, converse with real people (Skype, email, phone, but ideally Skype or phone or in person so that there is voice and not just text), clean, shop, walk. In your position you probably will soon be ready to volunteer somewhere helping others with recovery, which will be deeply gratifying for you, so routinizing such volunteering - putting money into the volunteering bank on a regular basis - will be a source of strength. I know for me if I go to the public library I tap into the strength of being part of a community of people who value knowledge and books and even though I do not have time to participate in all sorts of volunteering events our library hosts, I read flyers and it already makes me feel good - just knowing that the events are out there.
I speak to my former teacher on Skype every Sunday. He is very lonely and the conversations are important for him and I know he depends on me and of course I feel better knowing that I provide support for him; as for me, the routine of having our conversation weekly creates a structure (of course I always am happy to hear his voice). My adult son and I have been trying to talk each weekend via Facebook call, but it has been hit or miss; I hope eventually we get the hang of it - he understands me well and has his own mental health issues (anxiety).
I think for you it would be figuring out what you like accidentally or occasionally and then making a conscious effort of routinizing it.
Another very good older friend and essentially guardian angel of mine shared her trick and I packed away almost all my dishes and silverware so I am now forced to wash the dishes and not accumulate them in the sink. My roommate has a different solution - he buys (high quality) disposable dishes. I use a mixture of their solutions and since I started on this path, cleaning up after my meals has actually become a pleasurable task.
If you have extra time, you can try adult coloring, letting your thoughts take you anywhere they wish while you trace intricate design and select colors that appeal. I have read newspaper clippings that reported that the brain responds to this activity in the same way it does to meditation.
Since you yourself are interested in routinizing your life, you would enjoy reading this book -
Treating Bipolar Disorder: A Clinician's Guide to Interpersonal and Social Rhythm Therapy (Guides to Individualized Evidence-Based Treatment): 9781593854652: Medicine & Health Science Books @ Amazon.com - it is also the only evidence-based therapy that has been developed specifically for the bipolar disorder and authors explain how the disorder can be conceptualized as dysregulation of circadian rhythms. The therapy is an adjunct to pharmacotherapy. The therapy focuses on both social rhythms and interpersonal relationships and come to think of it, sometimes it is hard to separate one from the other - say, I go to yoga weekly but it is not just the yoga itself, it is also a few pleasant exchanges with our wonderful instructor, i.e. the social aspect of the happening, that matters. The book has a quantitative part that you will fill out, noting when you drink your first morning beverage, when you have your first interaction with another human (via any medium), etc. Then you compute your overall rhythm metric and you can track overtime how your life becomes more and more regularized. I think you will enjoy this approach.
