New to posting so not sure if this has been discussed.
In my younger days was into MDMA. Not your standard profile user as it was only with my wife (never set foot in a club). When I started taking them things were good and have some awesome memories but as so often happens with drugs, they tend to turn bad and the headaches started. Because I was ignorant of clusters back then I can't remember if they were clusters, My only memory is of excuriating pain that would last a few hours (plus the head was a bit munted at the time too !). I put the headaches down to over use and decided they pain was overriding the good times so have not used for about 10 years. The only other drug I was using at the time was weed. I'm still an occasional smoker and at this stage doesn't seem to be a trigger.
My question is could the over use of MDMA have been the start of my clusters or just ramped them up. Is there any anecdotal or medical evidence out there ?

Thanks Potter
At least one of my "sins of the past" is not going to come back to haunt me. Not sure about the ones!
