When i was using E more often, i was still smoking weed. Weed is what triggered the intense panic attacks, when i was sober panic attacks would rarely happen. How ever when i was sober just like you once in a while i would get an intense feeling of not knowing what is going on, just kind of being dissociated from everything. It depends on your usage, but it can take some time. Get some fish oils in you as well as multi vitamin, and a B complex vitamin. You should also get some cardio exercise, something i should have done when my anxiety was at its peak. I just read your original post again, so nvm you are already on the correct supplements. There is no speedy way through this bro, it's going to take how long its going to take. Just know that it will pass and, do NOT get on SSRI or benzo's. Sorry for being harsh but only failures do that, in the long run those medications will make everything worse for ecstasy induced problems. The only time you should get benzos is if you have non stop crippling anxiety, like you wake up with your heart rate shooting and such.
