If I were you I'd have benadryl, or diphenhydramine, handy for times like that. It's cheap, OTC, and it works to stop allergic reactions.

Also, you can get referred to an allergist and when you tell her/him what happens to you they'll prescribe you an epinephrine pen, they come in two's, for emergencies, like if your throat closed up. Just having one in my car and one by my bed makes me feel safe and I haven't had any more problems.

It takes time to heal, but you will. Hang in there.

 Hv, I am scared. I am the one that has been posting for months trying to heal myself and my family from toxic mold exposure a year and a half ago. I feel like I have the respiratory symptoms under control and maybe even the candida a bit, but my food allergies are out of control! I am allergic to most foods and now most vitamins/supplements. I thought I was improving with the grape bitters and homemade coconut kefir, but I ate a carrot today (which I have been tolerating) and had a mild reaction to it so I took the yucca root that I just bought since I am allergic to quercetin...BAD idea, but it is literally just yucca root in a gelatin capsule so I thought it was safe. Immediately, I was dizzy, nauseas with diarrhea, swollen face and tongue and felt like someone was holding my throat. I drank a ton of water and tried breathing through it. I am petrified to go the hospital as they will give me steroids and God knows what else. I don't know what to do next. I found a 5000mg Vit C powder that was just absorbic acid...should I try that? I have tried the amla and jiaogulan before with allergic reactions to both. I ingested the yucca about 3.5 hours ago so I am praying I am on the down hill now...I am still very lightheaded and nauseas though. Any help is GREATLY appreciated!

Do you have some watercress, eyebright or nettle leaf?  All of these are antihistamine.
