Weird roll - too much?

[Xeptic]

So, SWIM was out clubbin the other night, He took a pill he had left over from the week before. Was a love heart and they we top quality =)

So Swim takes this pill and it gives him a mild buzz after 45 mins, but he gets restless knowing its not enough for 8 hours of raving, so he goes off to buy some.

Some dude sells him 2 love hearts and a weird dove pill (which he cant find on pxxxxxxxxxs or anything) Its a dove, but the pill is slightly "deeper" than others, like 3/4 a milimeter taller when layed flat.

So Swim took the two love hearts 20 mins apart from each other (about an hour after the first)

The come up was extreme, Swim was practicly paralized.. swim felt like dancing but couldnt physically move fast enough. It felt good though..

After an hour or two feeling like this swim gained movement back and was able to rave for 2 hours.. there was no comedown as such, swim drunk a bit too much water and his bladder was on the verge of poping. Swim was unable to sleep well, and was sweating like a rapist all night (well.. morning/day)

Swim is wondering if this sounds like MDxx or were the pills dodgy?

Swim suspects ket.. has anyone else had an experience like this?
