I'm no expert but I have experimented with both drugs in question. You are playing some serious games with your heartrate. I suggest letting the meth wear off naturally. Drink a tall glass of milk and flush the meth in the toilet.
Hope you are feeling better soon
it was a fun trip. but i could feel my heart beat in my head and it sounded like the drummer from cannibal corpse doing double bass really quick. i dont think i'll do that again... ever.
