After eating some foods I feel like I haven't slept in 3 days and have to go to sleep. In the past I would eat yogurt which had whey concentrate in it, which I think is high in histamine, and it would give me brain fog, make me fatigued and very sleepy. I would have to go sleep for a few hours. If I ate it before bedtime then it would make me sleep 2-3 hours longer than normal. Yogurt with no additives didn't do this.

Right now I've been eating nothing but lima beans for years. I occasionally try another food but I don't tolerate them. They either give me heartburn, sleepiness or the smell gives me a headache. I've been trying meats and so far it seems chicken, beef, and pork make me sleepy and they all gave me headaches from the smell sometimes.
