Today i rolled on ex for the first time. the pills were hella shitty. i wasnt tripping balls like i thought i would. i could act sober. but i just felt a little happy. i took 1 pill then half then another half. so i took two all together. NOW the question. i heard your brain can swell on ex so i drank water and had a lot of salty snacks. but now that i came down. i cant sleep and im worried if i fall asleep my brain will swell when im sleeping. can that happen after you take it or just during the trip? and why cant i sleep? please serious answers only. and dont tell me not to do it because its my body and my choice.
