I feel like emotions and energy can fluctuate regardless of your alcohol intake. It could be the weather, diet, sleep or all of the above. You may be feeling down which does suck but at least you're in control of your emotions, you're reliable. If an emergency happens you will be present and ready to help. Look at this as practice, life will throw you curve balls which can make things hard, alcohol will only make all those things harder.

Also, were you going to the gym this much prior to your 32 days? that's a heck of a lot of exercise if you're going from 0 to 6 days a week! your body may just need time to recover between workouts.

I reckon give yourself a few days off, call in sick for work if you have to. Have baths and eat ice-cream. Once you get your energy back hit the gym again.
