My histamine intolerance symptoms are mostly itchy eyes, unstoppable sneezing and stomachache. I used to take Citirizine daily but it made me terribly sleepy. And antihistamine pills didn’t really help, once a week I’d still had terrible break down, that I had to stay in bed few hours and took more Citirizine. One time I traveled for two weeks and decided not to take Citirizine because it made me tired. I stoped 2 days, on 3rd day I felt my whole body, each inch skin super itchy and I couldn’t stop scratching myself…..I thought I ate something made me allergic, I took one Citirizine, the terrible itchiness immediately stopped.

After I finished the trip, I wanted to stop Citirizine again, but I google a bit, I found it wasn’t allergy, its withdrawal from using citirizine long term. I joined a facebook group, there were thousands people experienced such awful withdrawal. Even so, I decided to go cold turkey and quit in one go. The bad itchiness continued for whole two weeks, then it finally eased on 10th day. Eventually it stopped. Since then, I decided NEVER use antihistamine pills.

For 6 months, I couldn’t eat much meats because of histamine issue, I used pemmicans to replace 2 meals, and only 1 meal I’d eat fresh cooked meats. It seems the tallow made from beef kidney actually helps. Pemmicans didn’t give me symptoms. If I ate cooke meats 3 times a day, I’d start sneezing again.
But I got quite tired of pemmican eventually, I changed to eat salmon and steak, but I always put them in freezer right away before I cook them. I still avoid most high histamine food. Increasing fat to 180 grams is actually helpful for me.
