“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.”
