I'm not sure about the contents of cloud 9, but if it contains mephedrone (which is pretty likely), the mephedrone metabolizes into methyl-ephedra, which is similar to ephedra only 3-4 times more potent and is eliminated from the body pretty slowly. I have tried pure mephedrone myself and experienced the same problems of tachychardia and lack of sleep. If you're really scared, calla doctor, but in my experience you just need to relax (don't panic over the heart rate! ephedra is a stimulant and worrying will just make it worse) and drink a lot of water.

Hope this helps!

you did way to much!! your supposed to do very little and i wouldnt do it again if i was you unless your working third shift or in the morning time i wouldnt do it just to have fun to many thoughts go through your head i have a friend that does it an i think its starting to mess with his head pretty bad ..... only thing i could tell you to do is burn some energy off by running or some kinda of working out it will wear off

MILK OR chromium pocolinate?not sure thats how you spell but it is found in milk & will bring anyone down without harming thwm they use it in overdose cases

Start slowly, you can always increase the dosage, try a smaller starter blast, then give it some time to go to work. After waiting a little while you can better asses the doses outcome. as far as the pounding heart, and lack of sleep seams like a scheduleing problem. If timed correctly these sideaffects can be utilized for the greator good. I don't know how your partner feels about the use of this product. but mine was much less than pleased with me/it., untill she learned that it makes me horney, now its not such problem, my baby she's a horny one. understand I'm not a doctor (just like to play doc), but it has been my experance that allmost anything that can make her look up and smile that special smile, wont be looked upon with such a critical eye. I don't know just some thoughts from the other side of reality.
