I have to say that I think the reaction was due to drinking alchol and the alcohol mixing with the amytriptylline. I know you said that you stopped taking it, but unfortunately, not all drugs get washed out of your system that quickly. It will have built up in your system for the amount of time that you have been taking it and could still be there, so I am afraid that amytriptylline and alcohol are not a good mix.
Amytriptylline are vicious drugs anyway.
