I quit drinking wine 3 days ago and am exhausted and can't do Su Doku?! Serious question!?

I'm not a hardcore drinker but I am accustomed to having almost a bottle of red wine an evening, which is too much so I decided to go on the wagon. I am drinking lots of water and detox tea with lemon and cayenne and eating alkalizing food like asparagus. Does anyone know why I am sleeping so much (8 hours at night and I just took a 3 hour nap) and why I can't do 'fiendish' level Su Doku anymore? That one symptom may see odd but I normally do those relatively easily and just 3 days ago (the day after I stopped drinking), I found I could not complete one and had to go down to the 'difficult' level ones for any success. Am I releasing stored toxins that are making me lethargic and stupid?

absolutley not. You're brilliant. Maybe you should just accept the new you. Wine was your magic. So you gave it up. Now you will have to try like the rest of us beat those tough *** levels. Hey theres a good and bad to everything no matter what.
So you sleep more. Big deal. Thats your body catching up with all those rems you lost while you passed out every night. Eventually you'll catch up and then maybe you could celebrate with a glass of wine.
