After reading on this thread I have a few questions. Backstory: I've been using meth pretty solid for about a year an a half. Smoking up till august last year.. switched to IV bc I just didnt feel it from smoking anymore. I read up on here about water:meth ratio and I use around 30 water: .4 meth. (That's what I do now per shot). I literally feel a "rush" for about 15-20mins then nothing. No euphoria, no obsessive tasks, no needless talking, no staying up for how ever long.. I sleep every night. I have shot .4 multiple times per day just to feel that initial feeling. I kno my tolerance has alot to do with it. But after reading this thread I'm wondering about if my meds hav an affect on the "high" as well. I take 200mg diphenhydramine, 2mg risperidone, 400mg seroqeul, 45mg buspar an 20mg melatonin every night. I used to sleep like a rock but have gotten used to these meds as well. Could these meds be causing me to not feel the meth as much? I hav only 2 suppliers.. 1 is down rite now, the other has multiple sources of where they get it. The same stuff used to get me going pretty good so not sure if it's only caused by "shitty meth". Sorry if I've repeated some details I've posted in other threads i just want to cover all bases.
