Hi Dee! We have all felt this way many, many times. I can go stretches at a time without drinking, and i always feel so much better. Alcoholism seems to have a way of activatin selective memory in me.. I remember the misery, but it doesn't seem as bad as it actually was when you're feeling great.
Getting a support system is key for moments like these, as you mentioned. Sometimes i just need someone on the other end of the phone to remind me that once that flip is switched, I can kiss the next few days gooodbye and face a truckload of shame and loathing afterwards (I'm a binge drinker). Have someone you can call as soon as the thought pops into your head! You can do it :-)
