When I am slightly hypomanic and a little bit beyond, my intrusive thoughts and anxiety go away. However, when my psychiatrist reigns in my mood through an increase in a mood stabilizer, my intrusive thoughts and/or anxiety returns.
Just a thought...
Is it possible that your sense of self-confidence improves when you're slightly hypomanic? If so, perhaps some form of talk therapy could help you improve your confidence levels across the board and that might assist you in reducing your med levels.
Meantime, this discussion might also be of interest to you:
Do you need meds. You may find it helpful to follow up on the few people noted who are getting by without meds and paying careful attention to whatever alternate support methods they incorporated into their overall treatment to see if the same might work for you.
If that approach appeals to you, I would strongly recommend that you incorporate the alternate measures into your life first and if things are going well, then begin a slow and supervised med adjustment.
Best of luck.
