Hi - please never do that again. I myself had experimented with that pill when I was in my clubbin days but I and many I know of regret it!
I did it 5 times and the 5th was my last. I was given a pill that was either laced with something bad or just totally something different.
I developed panic and anxiety attacks. I had a bad trip! I freaked out and thought I was going to die. This lasted for about 8 hours then after wards I was really tired and depressed.
I was 24 at the time. I am now 29. I wish I never had done it. I am ok now but I had to deal with alot of anxiety issues and needed to go on some anit-depressants. I am not trying to scare you I am telling you the truth about this crap.
So, please never try this again. As for the constiptation.. Yes I remember experiencing that side effect while I was coming off it that horrible day which I will never forget.. I keep feeling I had to go.. But could not..Among feeling paranoia, and high anxiety, with hot and cold chills.
So take it from somone who knows ok.
I would consider really taking care of yourself now.. Eating very healthy. Getting alot of water into your system, taking some vitamins, expecially vitamin b's and getting rest for awhile. Take alot of vitamin c's and excersise.
Being if this was the only time you have done this.. And you don't develop depression/anxiety from this... Maintain a healthy lifestyle.
Just looking out for you..
Take care now.
