COMMUNITY SENTIMENT

Diagnosed inattentive ADHD here (M/34) and going through a difficult and stressful period in my life currently. Trying it with caffeine daily and it's been an absolute miracle for emotional dysregulation, ruminating/overthinking, stress management, and sleep quality. Extremely thankful for it right now.

U/THELAUGHINGMAN_1991

Life changing. Got me off benzos and stopped my desperate depression spirals that were a lot like bpd episodes. I'm not perfect, but I haven't had that kind of desperation in a long time. 200mg a day with my caffeine.

U/MIRWENPNW

I tried it for weeks and it made my anxiety a lot worse. Since stopping taking it my anxiety is much more under control.

Add context that might help others — skin type, conditions like PCOS, what you'd tried before. The more specific, the more useful.
