In my own experience, I found that lowering the dose to a level where I could function better but not relapse worked better but I had a lot of opposition from my psychiatrist. I found that the dose he thought I needed to be on was higher than I actually could manage more comfortably on. This is something that needs careful thought and consideration though and I'm not advising it, only saying what worked for me. I cut my dose down extremely gradually (following advice I found online) and I had two episodes where I had relapses which happened when I reduced it too quickly - something which some people might say was a reason not to do this, but I was determined because I felt my quality of life was so poor.

Combined with this I've been doing a lot of work lately trying to understand what stressors and triggers there have been for symptoms - largely by self-dialogue and checking out what thoughts I've got or have led to me being stressed (which seems to trigger symptoms). I have firmly believed that I got this illness due to emotional/mental problems caused by childhood experiences and key relationships - which other people may disagree with. Understanding more about this and trying to build in healthier strategies for managing - like journalling and supportive relationships seems to have also allowed me to drop my dose (as well as avoiding or setting limits on relationships that are unhealthy or stressful).
