My husband was the same way when he quit drinking, it was like when he drank the sex drive was normal and then when he didn't he was like a teenager, I just went with it, and he craved chocolate all the time. I could always tell when he wasn't drinking he was insatiable, but my job was to make sure he was happy, so talk to your wife, I am sure she doesn't hate you, she just might not understand, some people drink coffee like a gallon a day, lol but everyone is different so don't beat yourself up over it, is is normal for many.
