I was on meds for almost a decade, tons of different combos and the episodes of mania and depression were very consistant the whole time. I finally found some "other" means of coping or just living and honestly I am med free now, but I have not had an episode in about 8 months and for me that is my best track record.
While I realize my path isn't the path for everyone, one thing I do know, is that untill I found better methods of taking care of my whole "being" I didn't have any real improvements. I think mental illness and other illness or ailments of the person Sometimes really does require the persons being to be looked after from all ends. For me meds and therapy just wasnt going to be enough, no matter how hard I tried I was still neglecting other aspects that kept me in that circle.
So wether on or off meds, I think there are parts missing for treatment that we just can't get from a doctor. I wasn't an easy case I have bipolar 1 with psychosis. I felt pretty hopeless, but there is hope and I really believe there are ways to combat this effectively. Finding them tho takes time and perciverence. Ah and more time
