Hi Whiffle,
Welcome to SR. You've come to the right place for support. Like you, I too was tired of feeling hungover every day...one of the many reasons I decided I'd had enough and I needed to stop drinking for good, once and for all. This hasn't been my first attempt to stop drinking and become healthy again (physically, mentally & spiritually). SR has made all the difference for me. Stick around and you will see why. The people here ROCK and are so helpful. Also, take a look at the stickys above, there's lots of information here.
The first few days is the hardest. Just keep thinking "I won't drink today". Keeping busy, eating and drinking a lot of water helped me. If you're tired, take a nap. It will take your body a while to recover...be patient. Also, think about a plan that will keep you from relapsing. Lastly, there's no change without change.
Good luck to you on your journey. It's not easy, but it's doable and completely worth it.
