Has anyone ever heard of Ecstasy use resulting in migraines?

[RoboShindo]

Swim had never tried E's until about 3 weeks ago, he took one at 9pm, one at ten pm and had a double vodka and coke to wash the second down, he drank decent amounts of drinks (cola and water) throughout the night and felt great. He woke up the next morning with his body feeling somewhat tired but his mind feeling great and other than one day of what could only be described as mild lethargy, he was back to his normal self.

Fast forward to two weeks later, and Swim was ready to try them for a second time. These were different styled pills to the first ones (the first were white circles with a Euro symbol on them, the second were white circles with a heart symbol on them, If location is of an interest to you, They certainly aren't from the Yorkshire or Derbyshire Areas of the UK) Anyway, tonight he took three of the White Heart pills, his friend (a regular E-hound) took 5 over the course of the night, swim took one at 9.45pm, one at 10.15pm and one at 11pm. He was still feeling the effects at 6am but fell asleep for half an hour and when awaking at 7am for a piss, the effects were pretty much gone (hence the ability to pee returning). Anyway, when he woke the next day properly, at around 2pm, he felt good as ever, if again, a little tired. As the night came on, he started feeling incredibly tired and an awful pain in his head. This pain reoccured on the Monday night (the first was a thursday) and again on the tuesday night, but this time without the tiredness. He couldn't get rid of the pain using Paracetomol, Sinutabs (sinus pain relief tablets) nor co-codamol and has no other way to describe it other than a migraine. Could this be a result of the E or a mere coincedence? Swim hasn't suffered migraines since he was around 9 years old (10 years ago).

One thing to note is that swim realises they might not have been E on the second time, but his friend who used to take them weekly had no different effects or lasting hangovers than any other time he takes E. and two other friends who took the pills from the same batch the night before felt fine. The only thing swim can think of is taking 3 caused it, as its more stress than the body could handle, for a second time, but this doesn't explain the recurring headpains.

Any help would be very, VERY much appreciated. Thankyou.
