Yes, I got really freaked out when I realized how sensitive I was, in general, and the implications for both the food allergies but also in case of apocalypse - I realized I was completely dependent and not just taking them to function better, but to function at all. My environmental allergies are 100% controlled on Zyrtec or, alternately, Claritin (I switch off every seven years or so if one stops being as effective) plus nasal steroids unless I encounter something unusual like being in a place with a lot of mice or next to a freshly cut pine tree. I do have to take them year-round, though. I literally took them every single day for 20 years before I tried that SPT protocol. Given that, I was stressed about the OFC the doctor wanted to do for milk with the same three day no meds protocol. I just could not imagine, as I was reacting very sensitively to milk at the time. I did not test positive for it at all, either. I did not test positive on the SPT for shellfish (my other food allergy), but did in the blood test. I think I may be less reactive to milk than I was before now, though, so I might be willing to take the chance to see if I can relax a bit. I think maybe I managed one day with no meds but I don't totally remember.
I didn't realize that challenges were so common. I had the impression then that they generally did not food challenge adults as they are unlikely to outgrow the allergy. Maybe I should reconsider it if the doctor suggests it. I'm getting ahead of myself, though, since I have not even seen the doctor yet and found out if she will just blow me off.
