I want to know this as well, because I realize now after multiple meth binges, I overamp every time (IV user) thinking my shit was bunk when in reality, I always used too much right off the bat. Now I know less is more and will properly dose in the future, but considering I was blowing through a gram in 3-4 days I probably fried the fuck outta my brain.
Fortunately, I recover really fast, and get my shit together in a day or two after and continue on a sober life without depression and other side effects (I’m sure my heart fucking hates my ass even though I workout everyday), so my hope is my brain can still enjoy it correctly next time. I plan on waiting another 2 months at the least.
Gonna start at 50mg and if I can’t enjoy that I’m just gonna say fuck it and quit cause I’m happy enough without it
