I've had a terrible past few weeks dealing with nausea, stomach pains, horrible headaches, air hunger, etc, etc. I found out during this time that sulfur foods were causing me problems, but even after eliminating them the headaches, air hunger and nausea continued. I now believe the air hunger to be from adrenal fatigue, but the headaches and nausea are definitely related to histamine foods. I've been trying to research this and most things I'm reading seem to indicate if you are high histamine you are also an undermethylator. Is that true? I'm also reading that those who are high histamine should not take B vitamins or folic acid. Any thoughts on this? Maybe I'm jumping the gun here too. I did have a blood test previously and my histamine level was fine, so perhaps being high histamine is different from being intolerant?!?! Any input would be appreciated. Seems like everything is falling apart right now. The last few weeks have just been horrible and I'm trying to piece the puzzles together and make sense of it all. I have a doctor appt Friday and am planning to ask for some testing to be done. I'll start with a repeat of the histamine level. Any other suggestions for what to check? Thanks so much!
