Hi Rose, sorry you were feeling low. I hope things are looking up today.
I was a daily drinker but I think many of the tips still apply. There is a thread on here on things to do if you have urges to drink. They generally pass pretty quickly, you just have to get through it. Distracting yourself is one of them. Also if you drink in social situations, practice now what you will say if offered a drink. And I needed to avoid people, places and things I associated with drinking. Those may be different for different people. Hearing a certain song. A change in season, etc.
You can do it. Glad you're here.
