@maxload: thanks for the input. I was not planning on doing a back to back roll but thought that only doing a quarter of a tab the next day would be manageable. I think I'll be just fine in the end but would prefer in the future not to play with fire. I guess besides some light anxiety, light spaciness, and lethargy my only other symptom is similar to a migraine with a little bit of light sensitivity. Is this normal? I sort of suspect I might actually have a little bit of a migraine which is causing this, because MDMA acts on serotonin which also plays a role in migraines.
@smalldubster: Tons of water! I'd say I would refill my water bottle every 45 minutes or so, so each day probably consumed about 10 bottles of water. My pee was completely clear every day. Stupidly I didn't have much food on the first day, but learned from my mistakes the second day and made sure to take advantage of some of the great food stands they had.
Thanks for the input/ advice everyone. My line of work requires a lot of focus/ memory and I was just freaking out that I'd end up like one of the horror stories from people taking like 500 mg or something. I'm 22 if that is relevant.
PS: Just read the rules again and saw that you aren't supposed to use terms such as swim, apologies.
