People generally stick to meds once they start. It's a biatch getting off them, and I from what I've heard, I guess most go back after the 1st sign of trouble. I had a ****** time with withdrawls, and ultradian cycling, but glad I stuck it out. I don't plan on being medicated again, unless my dx changes from bp2 to bp1...

Ultimately, it's your choice, but you have to take lots of factors into account. Like support system, tools for handling symptoms, how your behaviour affects others, like are you a danger to anybody? Basically, it's the same things you take into account when being dxd, and getting medicated, but it must be fine-tuned in a sense. Being unmedicated doesn't mean shirking responsibility, at times you actually have to work harder coz you don't have a chemical safety net.

Only you can make the decision, only you know the extent of your struggle, and only you know if you are capable or not.
