Just do it man, fuck its not like crack ,trust me, I've done crack... Not everyday you get to use that line.
Its not an addiction thing, its just you brains reward system learn a new trick, a novel experience... but its not like you are fiending for more after the first dose.
You never ever have to do it again...and you'd be just fine with that.
Bout two weekends ago, I took 2 synthetic MDMA pills but didn't realy get off much, eventualy I ended up talking to a guy who handed me some MDMA in the dark.
I didn't realy expect it to be much, but apparently he had a shitload.. as the next thing he said was, take some now and keep the rest for later.... WAY TOO LATE...
He then told me that I just took as much as the 6 people in their party took toegether so far... Man I was railed pretty hard, but i was just fine by the next morning and drove the 80 miles home.
