This reply is waaay overdue, but last night, SWIM, did a gram of MDMA, re-dosing the other half about an hour later. You can feel the sunshine at night, but as soon as morning comes, you will convince yourself you would rather had not waken up. A. The physical effect of an MDMA hangover is really trippy..SWIM had mild hallucinations at night that followed into the next morning. 2. SWIM couldn't keep food or drink down, and had no appetite. 3. SWIM felt pressure on their head, and the head felt very stuffy. The most important thing for all of these things is that it's the MDMA that did it to you. You won't be depressed forever, just until your serotonin decides to replenish itself. Keep going about your day, and if people ask, (they probably will), you have the shakes and jaw cramps. This is probably the worse it will get when you do pure MDMA. If you do .2, .25, you probably will have a great time and not have to worry about anything the next day! (Maaaybe slightly more if you can handle it) Just buy a mouthpiece at the store before you go to sleep. & With the hangover force yourself to get water, and SLEEP! (Also, don't get any funny ideas about doing more when you're depressed. SWIM one time was irreversibly depressed for a month and a half.) And finally, SWIM will not do any other drugs besides MDMA. (No MDA, no MDEA, no MDNA). If you take MDMA cut with any of these things, your hangover will probably feel like you just got nailed in the face by a truck. So be careful. Plus, it's addicting.
