Basically, i got a pretty high tolerance to most “uppers” since I used to abuse quite a lot from age 13/15 but got basically sober over a year ago , i just take Vyvanse( prescribed but sometimes i take like 150/250 mg to be productive) a few days ago i got Ritalin la prescribed and wanted to get a bit more productive ( also a lil buzz maybe ) and ended up w out rly noticing taking around 600 mg in 12h … Now comes the crazy part . I’m legit fine ( tho I just read that that’s an od) like yeah I was energetic focused asf and a bit euphoric but rly not to crazy Is my tolarance completely fucked? ( I’m not abusing them to much like twice a month and otherwise i just take my 40mg a day) or what could it be . IM JUST KINDA CONFUSED
