I was just talking about the extremely sensitive gag reflex my daughter has! She does gags at all the things you described! Even dishes in the sink will do it. Yesterday, she said her car seat was too tight (it wasn’t but I think the clip that you raise to armpit level was too high) and she gagged! I always attributed this to genes. My husband used to be similarly inclined as a kid. He even threw up when the eggs were too runny! I haven’t noticed this only when lowering meds, it just seems to be constant! I know how scary it is to change and expecially lower meds. Try to trust the test levels. Take care, Julia
