Has SWIM done too much MDMA, or is it something else?

[stoned_roses]

Ok so SWIM started taking mdma about 4months ago (having done pills maybe 3 times 2 years before) and did 1gram in a single sitting over the course of about 5 hours. Wonderful Visuals and incredible buzz was had.

3weeks later SWIM did another gram, the first experience was replicated however the visuals were incredible, undescribable and overwhelming (but in a good, interesting way)
over the course of the next week, another gram was had, along with several pills at a party on the following saturday - a 1 week comedown was enjoyed

Towards the end of this week the MDMA and pills did absolutely nothing, no come up, no dilated pupils etc

Following this week, SWIM took a 4week break, with 5-HTP being taken everyday along with healthy eating and drinking.

After 4 weeks, SWIM deemed it long enough to do some more. 500mg of mdma was had on the friday night, it took an hour and a half to come up, and the buzz was minor and lasted only 20-30minutes before being back at bassline both mentally and physically.

Worried, SWIM took another 4 week break, which brought him round to summer solstice. 750mg of MDMA was taken over several hours, with the buzz only present for the first hour after another 1hr30+ til comeing up at all. After that there were some nice visuals thought nothing like the first 2 experiences.

1 week later and another 600mg is consumed over several hours, again only a 1 hour buzz after a long come up, but the remainder of the evening was pleasent.

Unfortunately, all of SWIMs friends do drugs all the time, and SWIM doesn't want to be left out, so last night 2x 200mg bombs and 1 pill were taken over 3 hours. The buzz from the first bomb was good, and it only took 20minutes to come up, lasted several hours with the pill and second bomb top up, it couldn't be described as "rolling hard" but SWIM was definately "on it". About an hour after the finaly bomb, the experience intensified somewhat, SWIMs eyes spending a reasonable ammount of time in the back of his head flying from side to side. However after about 20 minutes SWIM was sick, which instantly, and completely removed all effects, baseline was re-assumed.


What SWIM would like to know is, would you consider this usage, over the last 4months, to be excessive? To the point of causing maybe a lack of serotonin in his brain? SWIM was under the impression that a lack of serotonin would cause depression, or generally low mood. However, since that week where, in fairness SWIM did rinse it a bit, mood has been increased. Before SWIM didn't go out much, was reluctant to go the shops unless he had to etc... but now he goes out everyday (not to do drugs), goes to the shop at least once a day, and generally enjoys being out and about and feels much much happier in general. Surely this isn't consistent with having little to no serotonin?
Or perhaps the first few weeks of high usage has put in place a really high tolerance? But if so, how come the last three weeks SWIM has done MDMA each weekend with little joy, yet last night he felt more battered than he has done in ages.
SWIMs source is reliable, and is the same MDMA each time.
Dosage doesn't change much, 140-200mg per bomb/line whether its the first of the evening or the last.

Reading this forum SWIM has noticed some talk of medication and MDMA not going well together. SWIM takes 5-htp occasionally, it seems to make no difference whether he has one before after or during taking MDMA though. He also has VitB complex tablets.
However, he also takes Lymecycline tablets (anti-biotics) for his skin, and has been doing so since before christmas. Could this affect things?

SWIM has a cunning feeling that the reply is going to be "take a break for 6 months", which is fair enough, though he just wondered if anyone had any other suggestions.

SWIM thanks you for your time.
