Hi Shags,
Welcome! I'm sure many here will have much encouragement for you. I have a question and it's one I've been wondering about for awhile. This adrenaline thing-I can't understand it-alcohol is a depressant. Drinking caused the opposite for me. Now, if you're talking about the sneaking around, lying, and manipulating- that I can understand. It was sort of a challenge to get away with as much as possible.
Have you thought about non alcohol related activites involving action/adrenaline? I'm an EMT and it def causes a rush. Maybe not up to it now but maybe a future thought?
