I didn't feel any effects, but I did suffer a (mild) comedown. I shook randomly, and completely lost my appetite. I was awake the whole night, but really hurt my tongue and insides of cheeks by biting. I didn't notice this at all. Anyway, today, I started by drinking 2 energy drinks. In about an hour, my entire mouth hurt so much, that it was hard to move my tongue. I forced myself to eat, and it took a very long time, due to the pain, and the fact that it was hard to move my tongue and mouth.
Anyway, I know the hurting of the tongue and cheeks were due to the biting, but was the difficulty of moving my mouth due to the meth, or energy drinks?
Sounds like the meth worked just fine. You're probably having pain from grinding your teeth and tension in your jaw. It's happened to me on MDMA and meth.
Out of curiosity, why did you do heroin and meth together? Better to do them separately at first so you're familiar with the effects of each.
As long as you blow out your nose before snorting and clear your nose with some water or saline spray after it's really almost impossible to fuck up snorting shit. I think the effects were settle because the amount you took was too small. Plus your weight can definitely make you need more.
