I had pvc and svts and had heart surgery a bit over a year ago and said I wouldn’t do any more stimulants I ended up continuing with my use half a year later with doing vyvanse and and addy a few times and then Molly and ended up trying benzedrex which is not even good then crack and coke which I also don’t like cuz they too short but recently my Ritalin LA was upped to 40 and I been on a small binge but taken like 850mgs of Ritalin already and that’s like more than half script for the month but can my heart problems return I know the svt was caused by a extra nerve in my heart causing a electrical loop but the pvcs I don’t know the cause of (sorry for taking forever ti get to the point I’m on like 360mgs rn)

I snorted 270mgs all at once idk if that wastes it but I’d rather get it over with but how much is dangerous because I’ve been doing this for a few days and I keep increasing my dose
