Yesterday I was doing my daily duty of sorting through my email enjoying a glass of soda (Coca Cola to be specific); I was sipping on it and it was the only thing I had ingested for hours, out of no where my entire body started itching horribly (no rashes, hives, or flushing).  But by the time I made it to my meds and started to open the Zyrtec it stopped as quickly as it started.  I still took the Zyrtec to be safe and was fine the rest of the night.

I've never reacted to soda before, as time goes on can I expect to start reacting to new things?  Should I stop drinking soda or could it have been something else coupled with my drink?

I am finding this to be very confusing at times and I don't know what I would do without everyone here.

Lol, I think I decided it was the soda because we don't drink it at home.  We focus more on natural juices, soy milk, tea, etc; because we do not want our children growing up with a focus on soda (but be careful, for years we thought it was the right thing to do but about 3 years ago we had to incorporate flouride rinse into our daily routine because of the impact that even juices have on teeth); but my mother-in-law came out about a week ago and left a 12 pack of Coca Cola; and I finally caved in .

It was around 4:00, I kicked back on the couch with my laptop and I had not taken my meds at all that day except the ranitidine that I take in the morning.

I'm still experimenting with my medications to see what works best for me.  I think I will take a zyrtec in the morning with my ranitidine and then keep my pm regiment the same for now (zyrtec, xyzal, singulair, and ranitidine).

I'm a creature of habit so I take my ranitidine every morning between 6 & 6:30 and the full line up at night around 7...

Was your laptop directly on your lap, and, if so, was it hot? I find that this triggers my symptoms. I think it is the heat from the laptop. So now I have a lap desk to put under the laptop.

I cannot drink soda, as any carbonated drink bothers me. Like you, our family doesn't have it in the house either for the same kid reasons. Remind me, what is your diagnosis? Is it IA or Masto? I have IA and that  means that in theory I could react to foods that before I could always eat fine. I am pretty careful, so don't have many problems, though.

Do you get ill overnight or feel really sick when you get up in the morning? If not, you could consider moving your evening dose of meds earlier, unless you need a 12 hour space between meds. I take my evening meds at 4 pm. I figured I would rather feel good while I was doing things other than winding down and go to bed a fre hrs after the meds. I don't feel ill in the mornings or overnight, so it safe for me to take it that much easier
