Yes please...elaborate.
I remember before I started getting drug tests I have some ephedra that's suppossed to be 25MG pure extract per cap and I never got the feeling I thought it should give me so one day I said fuck it. I woke up, took four(100MGs), a few hours later took three more(+75MGs, for 175MGs), a few hours later took 2 more(+50 MGs, 225MGs), then that night I took 1 more(+25MGs, 250MGs).
30 minutes or so after taking the last one I literally felt like I was going to have a heart attack. It scared the shit out of me. My heart was beating like it does when you're really really winded and every throb is painful. It fucking SUCKED.
