Stay at 150 xl or up to 300xl?

Hi, I'd take 100mg lamictal and 150xl wellbutrin for my Bipolar type 1, alongside me being Autstic, and strong ADHD traits, Plus have Mild cerebral palsy, Anyways, from the first dose of wellbutrin it's was like a switch went off and for the first time in awhile I'd have had enegry and drive to get task done, Still have energy afterwards I'd started to take showers more often instead of every 2 to 3 days, I'd didn't wanna go to sleep as soon I'd got home from work, Wanted to actually go outside and explore my city beyond my neighborhood Got back into my interests, Was able to watch TV and movies and read books, Without having Squirrel Brian 😂 I'd have had strong ADHD traits and it's help somewhat as well I'd don't know if I'd should go to up 300xl, or stay at 150xl
don't wanna get manic, Wasn't manic when I'd went on 150xl, which is very good Might fellow the "if it ain't broke, Don't fix it" Not sure if 300xl would help or hurt? Has anyone stayed at 150xl, and didn't up to 300xl?
