Have not drinked milk for a long time. eaten food with a lot of milk in the last couple of days. right after : fatigue, depressed and itching. idea?

enzymes: Eating a meal and drinking milk can cause an increase in circulating serotonin and tryptophan. These chemicals can make one want to take a nap. The itching may be related to food allergy to either the meal or perhaps the milk. Taking a siesta (nap) can help restore the body and get back to full functioning.

Intolerant: You could be lactose intolerant or sensitive. Depression and anxiety have often been associated with food allergies and sensitivities. Please go have this checked by a physician.

You may be allergic to dairy. This is different from lactose intolerance and can be determined by an Allergist/ENT.
