Well here's my 2 cents on this situation for you. When I was around 18-20, I gobbled lots of acid, like probably well over 150 hits - never more than 2 at once, and never more than every weekend though. But I felt like head was all screwed up for some time after that. I started seeing permanent visuals and just had generally not right thouughts, though never had a bad trip. Anyways, I stopped eating acid (though I've had like 3 hits over the past 2 years and for reference I'm going on 27 now) and my head feels so much better. So just give it time, I think it will go away. The only residual effect I might have is what I call "tv screen" vision - where if I look at a white blank wall I can kind of see snow from a tv screen. I told my optometrist and she gave me a very funny look. But I can't really say that's from acid.
To answer the other part of your question, I've had great success with overseas pharmacies. I've ordered lots of different drugs from them and have yet to have a problem. i've oreder codeine, xanax, valium, bupe, etc.. It's always come in about 2 weeks and the prices are pretty good if you shop around. Certain pharmacies have much better reps than others, so just shop aroud. In the 10 times I've orderd, all 10 have come through in about 2 weeks.
And finally, I don't recommend dosing that much in benzo's - that's not safe - just use lots of will power before you pop that pill to calm you down.
Good Luck!
