I forgot to say...
Maybe you can try eating eating healthy, meditating, tapping (researching how these affect bipolar and mental health) - basically see how they help before you get off meds, and maybe try going off meds while stationary (but again please look up the best way to go off meds - like everyone else said it can be pretty terrible if not done right). Maybe these other practices will help the transition and help you handle any breakdowns.
Or just stay on meds, stock up and bring them but also try these other practices because road is hard on you sometimes and also magical. Traveling itself is kind of bipolar haha. Physical health will help mental health always.
My ex-partner is very bipolar and wasnt medicated when I met him nor when traveling. His mood swings were rough (and because he didn’t really work on how to better handle it and prevent himself from saying a lot of fucked up shit - we broke up). When shit got rough it affected him intensely. Everyone’s different with how they express their highs and lows, but the point is it could be hard for you and the people around you. You wouldn’t wanna lose your road dog over a breakdown. (Not to say that what happened with my roaddog but after enough emotional abuse I had to get our - of course I have my own flaws too)
I also believe that I’m slightly on the spectrum for being bipolar and I’ve used healthy food, breathing practices, & traveling to cope. Essentially healthy food and movement, even if that movement is yoga helps my brain. I accept that I will have highs and lows and i work with them. Luckily my lows are suicidal - although I’ve been through depressions like that in the past - which is why I’m a health nerd now.
Aight there’s my ramble
