Well,I'm thinking that you liked the crystal. From the sounds of it A LOT. However, if you're asking if there is something physically wrong with you, than no, I don't think you have much to worry about. Stimulants are known to have that kind of effect (well all drugs of addiction-though I've experienced it most with stims)-it doesn't have to be tingling, it could be any sensation associated with excitement and anticipation. For me, with coke primarily as I live on the east coast, but with crystal and some other stimulants, I would often have severe stomach cramps or even nausea/vomiting before I used/when I went to pick up.
So do you have something to worry about? I would think addiction to meth.
