Hi
Its good you are stopping so young - good luck! I went to Trinity over 20 years ago (engineering too!) and I wish I had not drank so much, I would have had such a better experience if I had not be focussing on the next party or trip to the pub to get drunk, not to mind dealing with consequences of drinking and the morning after misery and paranoia! I was already an alcoholic by the time I left.
20 years later, I have had extended periods of sobriety, but have drank on and off for the last 6 years. I am now committed to doing whatever it takes to stay stopped. I was a binge drinker and am on day 7 now and attending AA - that's how committed I am as I was always ambivalent about it. I must put my sobriety first, or my life will go down the tubes completely.
Why am I writing this? Because I believe if I had left alcohol behind me at that point in college, my life would have been so much better.
Good luck in your journey !
