SSRI's will pretty much stop the effects of MDMA and other stimulants, altho some people say Prozac/Lovan doesn't effect meth/speed. MAOIs are rarely prescribed and if you do get them prescribed say you eat a lot of old cheese and red wine and heard it was bad.
MDMA isn't something you should be taking for at least 9-12 months if you have anxiety. It definitely makes things worse, especially when weed is involved. Look at all the evidence.
As I said before, SSRI's make MDMA and psychedelic not work. The only drugs that will work is G, and you should keep away from that as it is addicttive and too easy to slip into using it a lot as it is the ultimate care-free anxiety-relief drug... but the rebound sucks with heavy usage.
Just quit the drugs man, and see how it goes,m if it doesn't get better, see your doc and ask for an SSRI. tell him if you're having sleep troubles as some meds like Prozac, Cipramil and others can keep you awake. Lexapro is a version of Cipramil with less side effects but you will gurn in your sleep and its a very weak SSRI, doesn't work for much people at all.
As i said in the other post, Avanza is a good choice. I'd stay away from doxepin and the other TCA's as they tend to make you need to drink 2 litres of water a night and make you so groggy you can't wake up in the morning and slowly build tolerance, but don't really seem addictive besides some rebound.
