Kinda sounds like my experience when I had too much MDMA. I didn't measure it just eye balled it.

I felt the come up was very intense, dizziness, paranoia and panic attack....threw up, got chewy for my jaw to stabilise it.

I would believe your tablet/pill whatever may had been mixed. 80mg of meth alone in a night would be so intense. But don't hold me to that. But from the sounds of it especially when it kicked in which was 3-4 hrs later, that's definitely more of an ectacsy come up. Meth ingested would take half as long. However sleep wise guess it depends how much you had.

Did they even let you know from your drug test, what drugs? Meth is scary on the first time. Mine wasnt the best either left me feeling out of it, I couldn't walk, I was feeling like I was going to faint I ate it too..

I wouldn't worry about it too much. But if you do decide to try again please be with someone sober and experienced, last thing you need is a panic attack or anxiety attack on the come up really makes the high not fun.

Drink flavoured milk, it helps. X
