just wait till your honeymoon is over. i've done tons of the stuff and it does cause heart pains later (and during from excessive heart rate) and wierd side effects like breathlessness and dizziness plus paranoia and insane wank marathons.
overall an addictive but ultimately dangerous drug
i second this. i finished about 3.5 grams in 4-5 days (i honestly dont remember I was so fucked up), and when I woke up after the 4th day, my chest hurt, was switching between pain and numbness, and the pain/numbness would shoot throughout my left arm. i was also extremely short of breathe and fatigued the whole day. looked up the symptoms and the first thing that popped up: heart failure. sweet, im gonna die!
wanna know the kicker? the day i woke up to discover my heart was possibly failing....was my 21st birthday. SWEET DEAL! i spent my entire 21st birthday moping around in a state of pure fatigue, praying to god i didnt have a heart attack and wake up in the hospital with a pacemaker inside of me. fucking scary shit.
i completely stopped all 4mmc usage after that, and havent done it since. not to say i wont do it again sometime in the future, but please dont binge this stuff.
I honestly predict that half of the UK, and 1/7th of the US will drop like flies in 20 years, and because 4mmc will have been illegal so long then, no one will make the correlation.
And we used to think energy drinks were bad for the heart :D
....
still... the high is fucking amazing. its like a short lasting meth, that has that perfect little hint of enactogenic activity that just makes you fuzzy all over!
