I think I might have overdosed on Amphetamine, by accidentally taking 1 gram Hi, I ordered from a vendor who either messed up my order or sent me 5 capsules containing 1 gram of Amphetamine (I have no tolerance). 

I took the capsule thinking she messed up and send me a capsule with only 100mg.

But then I got to thinking and opened up a capsule and it looks like it contains 1g amp.

So I immediately 1) took a shitload of Clonaloam (to slow heart rate), 2) drank alcohol to potentate the benzo, and 3) ate a lot of food and milk. 

So I am not sure of I took 100mg amp or 1 gram. This was 50 mins ago, so far I feel fine (no heart problems). Anything I watch out for before calling an ambulance?
