Intense cravings come and go for a while, but usually the worst of them only last a few weeks at most. All I can say is if you do plan to continue drinking early on you are probably setting yourself up for failure. The key is to take it a day at a time. Don't think about your life being boring. Just focus on today. It will take some getting used to, but trust me sobriety is so much better and more rewarding and doesn't take away your dignity and integrity like drugs do.
I guess all I would say about bumping into someone at a meeting is obviously if they are there they are looking for help too. They want to quit same as you and maybe you will make some connections you never thought you could have. Feel free to go at it alone, but I wouldn't rule anything out. If you find yourself continuing the cycle and not being able to stop more support might be needed.
