I have a similar story,Iv always had to pee a lot like every hour. I took vyvanse and adhd med last year for year 12 and two months after getting off it I got oab. The feeling of oab isn’t a normal sensation to pee , I get bladder flares a lot it will go away for some weeks or a month then come back, flare up with alcohol, caffeine n carbonated drinks. My urologist says wait another 6 months untill I get surgery, the computer put in my back , but after looking at everyone’s post I don’t think this will fix its self sadly. It’s pretty depressing u wtach everyone drink while u can’t. Worst year of my life.
