DH is mid-30’s, fit and healthy, does plenty of exercise, and not overweight. By about 3-4pm on a weekend, or after he gets home from work during the week, he is absolutely exhausted - tired enough that he could just go straight to bed. He’s been like this for a while, and we put it down to lack of sleep with our DS, but he sleeps through now so DH is getting a full night’s sleep pretty much every night. Is this just normal? Could it be diet-related? We eat a pretty good diet I think, but I’m wondering if a multi-vit might help, or if he needs to see a Dr to see if there’s anything else going on?
