What got worse for some people
In their own words
“Combined with Sulbutamine was like a laser cruise control. I feel like a six year old kid in focus terms again.”
“I'm more motivated than usual and It's easier to focus on tasks... but on some days, it felt like someone had taken a sledgehammer to my head; my mind felt noticeably clouded.”
“Sulbutiamine was supposed to help with anxiety but increased it tenfold. It also gave me very bizarre and disturbing thoughts.”
“The effects are noticeable. Mild euphoria and good mood, music sounds better. Not very good on your liver, hence I dropped it.”
“Sulbutiamine: Noticed it for 1 day (Placebo?) I tried varying my dosage and different times of the day, 1x morning, 1x afternoon, etc and never got anything else out of it after day 1 or 2. Gave up.”
“I took between 300mg and 600mg right before falling asleep and I noticed my mornings were spectacular.”
