Timing is everything, the first time I visited Ibiza I came just to party and get destroyed. I took pills everyday for 6 days straight, first two nights the buzz was great but eventually they stopped working and by that point I had not eaten for 2 days, thankfully their were alternatives. I didn't know any better really and it could have been much worse I guess, my seretonin was completely drained and it took weeks to build it back up again, I cried like a baby for a few days upon my return home and even missed my initial flight back (we all went abit mad, but learned our lessons). By my second trip a year later I only rolled twice and left 6 days between taking them again. They were the Donald Trumps very strong.
