Last year I tried crystal meth based on curiosity. Up till yesterday, I only did it couple times on rare occasions, not more than 10 times. But lately, since the 2 times before this I used it, everytime I did it and missed couple hours from meal time I ended up in a bad gastritis. I felt like I want to throw up and such. Could it be the meth effecting my stomach in anyway, or is it just an ordinary gastritis?
