i wouldn't want to do more than 2, tops 3. unless i had lots of pot and some benzos to come down on.
either that or some clean mdma pills. the type of roll where it's just smooth relaxing waves of pleasure.
last time i rolled i took one mdma/speedy pill and one mdma/mda a few hours later. it was ok for the first half of the night, but once the sun starts to come up i think it's time to give up chasing that first high.
E is a great time but it's got to end sometime. i'd rather have a few good hours and end it, than have a few good hours followed by a half rolling cracked out nasty feeling
