Combinations - Methylone and nitrous

[psitryp]

SWIM decided to take 190mg methylone the other day. The plan was to combine the methylone with nitrous (whippets).
SWIM inhaled the first balloon a couple of minutes before he downed the methylone just to get into the mood.

At +40min SWIM inhaled another lungful of the funny gas. After holding the nitrous for 10sec a strong tingling sensation spreads throughout his body. But then something weird happens. SWIM is almost passing out and all his muscles contract, especially the muscles in arms, fingers, hands and stomach. So SWIM exhale quickly as hell and the passing out feeling dissipates but the increased muscle tonus persist. SWIM gets quite a bit worried to say the least. His fingers is bent inward and very cold and he can straighten them out with some effort.
The muscles relax gradually over a couple of minutes and SWIM make another testrun with the gas. SWIM now only takes 1/3 of a full balloon and gets very funny and giggly but with some minor muscle spasms still.

So what did SWIM learn? Somehow the nitrous induced intense muscle contraction when combined with methylone. The largest dose tolerated was approx. 1/2-1/3 of a whippet. The nitrous intensified the methylone for a couple of minutes and seemed to prolong the total experience as well.

A good combo if used correctly. Perhaps this is just how SWIM reacted and others will react differently.
