Congrats on 8 days. Nice start.
Some of this is dealing with your expectations. You thought you could quit drinking, and right away, you'd feel better and happier than when you were drinking. That's the problem. You should expect the 1st 90 days to be a big adjustment period. Your friends who quit cigs didn't say "i haven't smoked for 8 days. I feel like crap. Cigs are good for you and make you feel better."
Also, don't compare the peak of your hubby's evening alcohol buzz with your early sobriety evenings. Instead, compare the energy you have when waking up without the morning detox while your husband moves a lot slower in the morning.
What were the reasons you stopped drinking 9 days ago? Remember those reasons, they're still valid.
At least give it 90 days. That's only 1/4 of one year. And you have 70+ years. 90 days is only 1/280th of your life.
