I have sleep Apnea that is totally different. I do wear a mask at night. I fought it for years but finally decided to get tested because of being tired all the time and keeping hubbs awake. I have just figured out I am corn intolerant , I figured it out from a trip I took up north. I bought a bag of Frito Corn Chips and snacked on them on the way up north. That night I had such cramping , gas and the next morning was big "D" I didn't figure it out then, then there was another time same thing, I had some Frito's and I was in so much pain that night I almost called 911. It was mostly gas but OMG it was so painful , so I knew it was the corn chips. Then one day at a friends I had a coke. Yup it sent me to the rest room, I assume because of the Corn syrup in it. So I try to avoid Corn as much as possible. Crazy stuff!!
You should get a blood test done to figure out exactly what your allergic to. In my case I found out that I have a moderate intollerance to wheat, and a low intollerance to dairy and yeast. However, its how my body decided to react to these that is important. My throat swells up, which actually isn't a problem until I go to sleep. Your throat relaxes even more when you are sleeping, and as a result my breating way is blocked. I only suggest this to you because all of my doctors were strongly suggesting that I have sleep apnea, but after cutting the alergy foods out of my diet and taking a sleep apnea test they told me that I definatly don't have sleep apnea. They are all just quick to push people into that catagory because of the connection with sleep.
Mine was so bad for a while that while I was walking around durring the day, I would feel a little chocked up here and there, but didn't alarm me cause I would just swallow and clear my throat and not think much about it. I just never made the connection between what was sometimes happening to me durring the day, as also being the same thing that was heppening to me at night.
I have a MODERATE intollerance to wheat, yet its bad enough that if I eat a mcdonalds burger in the day, I will be waking up at night not able to breath.
I have a LOW intollerance to dairy and yeast. Pizza kills me, the only thing on there I should be eating are the toppings, no crust and no cheese.
You might think that a moderate intollerance would allow someone to eat a little bit of it, but it would appear that my body has chosen to react to these in a very rare way. Having anaphylaxis from food alergies is RARE, and its hard to me to explain to people that even though there gluten free food should be safe for me, what matters if wheather or not it has wheat, not gluten. Mine is life threatning, so I have to take an epi pen with me and stab my leg in an emergency.
