Serper, I have not read your background but I can tell you this: You are damn right this is serious. You could have killed someone or a family. I have every sympathy in the world for your addiction problems. I am also an alcoholic. But if you are driving around out of you mind drunk and high then you have a major problem and it needs to stop.
Coffee is not causing this and neither are the cigarettes. The booze, benzos and weed are. If the booze is leading you to weed and benzos then start with that. Whatever way you cut it all three need to go. If you are an alcoholic and that is your main problem then start with that.
You joined a year ago. So you now know full well that moderation does not work in virtually all cases and it does not work for you. So therefore you need to quit completely, forever. This is a truth that you need to face and you need to quit immediately. See a doctor if you are conceded about DTs, by now you know all about those also.
This means doing it the hard way: Quit, draw up a recovery plan, never drink even a single beer again ever, identify your triggers and plan around them.
Smoke or don't smoke and drink or quit coffee, whatever helps. Whatever stops you drinking. Pick up new activities, eat as much as you want or need. Whatever it takes just don't drink. Consider attending AA, it sounds like you need as much help as you can get so I would recommend it. Again, whatever stops you drinking.
Your way does not work. You need help and support and an iron resolution never to drink again. So here is what I do EVERY DAY and it got me to 11 weeks:
- use AVRT to combat cravings and keep my addiction at bay
- attend an AA meeting for group support and to understand RECOVERY as opposed to ABSTINENCE
- read and post on this site to learn more, engage with people and to help where I can
- read the AA big book and research online
All in all I spend 3 or 4 hours EVERY DAY on my recovery. Obviously I will not do this forever but in these early weeks and months I personally feel it is necessary. And do you know what, if your alternative is killing someone else in a car crash then it should be your priority too.
