We hear you ontario, loud and clear. You give us the perfect reason to be careful, check our pills and not do amphetamines multiple times a day for 8 months straight.
You appear to have been a very heavy user of amphetamines (not just MDMA) and you must understand that few people use ecstasy to this extent because eventually MDMA just stops working due to low levels of serotonin in the brain.

Moderatation coupled with the other tips I have mentioned (5HTP and multi-vitamins) assure that nobody else will end up as you have.
