I get more tired at night when I'm not drinking and I usually go to bed a bit earlier. But that's what the cleanse is about. Winding down, calming down, slowing down. Getting in touch with how you really feel about things in your life - without the camouflaging (if lovely!) effects of alcohol.
But be prepared to feel a little drowsier at night. There are 3.5 grams of carbohydrates and 70 calories in a 100 ml glass of white wine. Uh ... it's been a looooooong time since I've considered a 100 ml glass of wine anything but an insult. That's equivalent to 3.4 ounces - so maybe double that or even triple it if you're SuperSizing somewhere to make a full glass of wine. That's a lot of energy you won't be ingesting every night you're on a cleanse. So keep stocked up with other drinks: teas with healthy sweeteners or a little caffeine, juices, soda pop. Take it easy on the pop obviously. No use curing your alcoholism and getting diabetes. But don't be afraid to treat yourself either. If there's any time you deserve it, it's now. If the juice doesn't cut it, go to sleep! Rest up. Your body will appreciate it and you'll feel so much better throughout your cleanse and after.
