Hi SoberonSaturn, and welcome! I echo Arpeggioh, a doctor's appointment is a good first step, especially if you've felt physical symptoms of withdrawal on your previous attempts to stop drinking. And, well, it's always a good idea if your doc has a full picture of your health and habits - that way they're best equipped to help you be healthy.
Do you have a plan for moving forward with your sobriety? SR is a great place to get support from people going through the same thing as you, and there are tons of great resources here. Of course you know about groups like AA and Smart Recovery. There are lots of good books out there to get you motivated. (There's a thread here linking to tons of them). I guess my general advice would be to pour as much energy (or more!) into your sobriety as you did into your drinking. Best of luck!
