Orlanda, this is excellent and supportive advice. I just want to mention, as far as diet goes, that it's really important that long-haulers eat anti-inflammatory AND low histamine. I already ate pretty anti-inflammatory in general (no dairy, NO sugar, lean meats, lots of veggies) but the low histamine foods are VERY specific. For instance, avocado is high in histamine and my symptoms slightly returned when I ate too much avocado one week. Tomatoes are also high in histamine. That was surprising to me! and a great reminder for me that even though my symptoms are now 90% gone -- as long as I stay in balance -- they can come back quickly by eating the wrong things.

So, along with reducing inflammation and histamine levels in the body through diet, taking histamine blockers for a short period of time also helps. For instance, Pepcid AC (H2 blocker) as well as Claritin (H1 blocker) daily.

Those who follow the MCAS protocol often see very good results as well, because MCAS treatment is also all about reducing histamine and inflammation in the body. I've shared a few links below. All the best to you!
