It is OK to feel hopeless right now. Because then when a hope
does enter your brain it will feel like the biggest accomplishment ever!
While I have never gotten a DUI, I did take a long-acting sleeping pill after drinking a bottle of wine. This in itself would not be such a big deal (totally warped thinking) except that I proceeded to deep clean my entire house in a 6-hour time period. That is completely unlike me. When I woke up the next day I asked my husband, "Oh my gosh did you stay up and clean all night? It is such a nice surprise and so unlike you!?! What's up?"
Alcohol, among other things, is just plain bad for us. Hang in there. You are processing and it just takes time.
