I'm a little tired myself now at 9 days. It takes time to let the body get back to doing what the body is supposed to be doing. How about a trip to the doctor for some blood work? Alcohol does quite a number on us. Just got mine back. Liver enzymes in the high normal, cholesterol up, but otherwise OK. I've found that if I get home from and start doing things instead of just watching TV, I feel OK. Maybe just a little excercise. Everyone I've asked about this says it will get better, just be patient.
Hang in there. You'll be fine!
