Hi,
swim had a similar experience, first time with mdma
5 guys had 2 little bags containing pure MDMA powder(I know that it is virtually impossible to get PURE mdma, but they got a white powder with little christals, it was as pure a as one can get it, they call it molly I think) anyway. they were told that they should just lick the tip of their index finger and dip it in the bag. They took each one hit, then 40 mins later, another dip and since it did't hit them cause they had eaten a lot before the first dip, they took another 2. thats 4 index finger dips in 75 minutes. about 25 minutes later they were rolling and everything was great. swim ended up taking 8 dips in 8 hours and swim had about 2 lager beers, and swim took a hit of pot about 30 minutes after the effects of the last dip were wearing off.
At the next day, swim smoke more weed. The point is that the first night after the mdma experience, nobody got any proper sleep, swim had to wake up every hour or so to take a leak. the second night he slept properly, about 7 or 8 hours but he felt funny...
Its been 4 days and swim still feel a sort of pressure throughout the head, it doesn't hurt, it just is. swim feels as if somebody was placing both hand on swims head. He feel pretty tired all the time and sometimes even gets a glam of dizziness. Swim realizes that he hasn't rested properly and that his serotonin levels have a long run to get back to normal, but he is just worried that nobody else feels anything wrong and that swim might feel like this forever... Its been one more day (swim wrote this yesterday, but swim couldn't post it) since this happend, swim no longer feels dizzy or tired, but swim still feels the pressure, swim has realized that its because swims head is pulsating, Swim can feel the arteries on his temporal lobe pumping blood, swim can feel his heartbeat on the temporal and on the frontal and occipital lobe. It doesn't hurt though. Swim would like to believe that this is because serotonin levels have an influence in blood pressure and that this will disappear in a few weeks tops. Or as a worst case scenario, that as stated in another drug forum, some of swims axons got destroyed and they are re-wireing so swims body is sending a lot of blood to the head to make the repairments.
