I don't know why but in the last week I can't digest milk. Same brand I've always used. All I did was try magnesium for like 3 days. Decided I didn't like it and stopped. And tried eating some green vegetables once. That's all. Everything else the same for years. And now I get diarrhea every day. I tried taking some activated charcoal to get relief for a while but I can't take it everyday can I?. Then I tried to eat potatoes and no milk. Diarrhea stopped. What the hell is going on and what do I do? I been drinking like 1-2 liters of milk every day for 3 years I don't know what to eat. I'm hungry and I crave milk but I know it's just gonna give me diarrhea.
