'Don't drink'
Easier said than done when hungover. On the weekends I always used to practice hair of the dog.
My tips:
Find anything, and I mean anything to do besides drink. For me the below works.
1. Playing video games. Immersive ones that take a lot of attention.
2. Read. I read a lot. Hard to do drunk.
3. Physical activity- lots of projects around the house to be done.
4. Cleaning. This one really works for me when cravings are super intense.
5. Do you have a friend who is recovering from alcohol? If so call them and commiserate on how hangovers/withdrawal is the worst(this helped me through the first 2 or 3 days a bunch)
