My husband is 57years old. He has always been a slim man, however, in the past year, he has lost about 30 lbs, he has problems staying asleep, after about 4 hours of sleep. He eats only one meal a day. He drinks coffee all day long. He eats chocolate or sweets constantly.He also has no sex drive anymore. He works long hours, and used to be full of energy, but now he comes home and sits in his recliner,gets up to eat and gets back into his chair. He refuses to go to the dr, what can I do?
