Interesting thread. I only recently managed to get ahold of it (as non-MCPP pills had been impossible to get ahold of for months in Glasgow), and to me it felt like a very good pill. But obviously, since it's not cut up with other things like speed, you do find yourself 'monging' a lot.
Some times I'll just want to sit and vegitate, other times I'll be dancing all night. I really don't know what factors differ, it may just simply have been the mood I was in/how tired I was before.
There is a definate temptation to take something else like coke to keep yourself awake, but I've managed to resist the temptation so far. I may have a cheeky line at NY, though, if I can get a hold of it. It's going to be a long night!
