Doesn't surprise me at all, these igmos that claim to be "allergic" to all sorts of crap, not having the faintest fucking idea what real allergy entails -- before I started taking my daily Zyrtec so we could adopt the stray kitten that turned up, if I was in any home that had even one cat, within 10 minutes my eyes were itching and burning, my nose running, my asthma demanding a puff of albuterol -- idiots would offer to put the cat in another room, despite the fact that the cat's hair was EVERYWHERE, and it hasn't got a fucking thing to do with "dander", it's the detergent in their saliva that they've coated their entire body with, with all their licking. I used to have the same allergy to fresh dyes; couldn't spend 5 minutes in a fabric store with my grandmother, even when she making me some gorgeous garment and wanted me to choose the fabric! I don't think that particular allergy bothers me anymore, but the cat allergy sure does; despite the daily 24-hr Zyrtec, I still sometimes need a supplemental dose of benadryl, when my eyes are giving me fits.
My sensitivity to caffeine, I'm pretty sure, is due to my IBS; anything at all that stimulates or agitates my colon, makes me deathly ill, and I think this is exactly why I was so sensitive to nicotine when I first started vaping -- nicotine stimulates peristalsis, and though I smoked for 39yrs, the last 20+ were ultra-light cigarettes, which don't contain much nicotine -- even 12mg ejuice made me horribly sick. Once I was completely off cigarettes, I was able to slowly ease up to10mg, but never more than that. This also explains why, after my appendectomy, I was DEATHLY sick for 4 days, and the entire recuperation took more than 6 wks, though I had the laparoscopic type of surgery. Nevermind stimulating or agitating my colon; sepsis in my colon and then removing a chunk of it surgically, was a great deal more than my colon was prepared to deal with!
