Constant burping symptoms and conditions

sex drive is slowly dwindling away, that is not like me at all, but then its hard to feel sexy when i'm bleeding all the time and my nether regions smell not to pretty. lol.
other side effects to date are
depression, anxiety, agitated, joint pain, constant bleeding, unpleasant smells, low libido, pains under ribs (not sure if down to mirena)

My husband suffered for a full year with constant burping--not reflux, not heartburn, just air, like colic. He was so bloated that it was painful for him to sit. He went from doctor to doctor, and even to a GI who suspected Celiac's. He also had a feeling that his throat was constricted, and once went to the emergency room, afraid that it might close up. The doctors found nothing.

He has a severe dust allergy (it causes hives, no respiratory symptoms) that was diagnosed last year, at which point he was prescribed Zyrtec and Singulair. He mentioned the prescriptions to every doctor he saw (this is in New York, not the boondocks, btw), and every one said it can't be the Zyrtec or the Singulair. It should be noted that we eat all natural foods, no white flour, no white sugar, so we knew there were no artificial additives that could be causing his reaction. My husband even tried cutting out dairy, then wheat, then all gluten, for over a month.

Finally, about five weeks ago, he told a cousin about his mysterious symptoms, and she asked if he was taking Zyrtec. He said yes, and she said he should try going off it because she'd had a similar problem with that drug. He did, and within four days, the burping and bloating stopped.

Because his itching was uncontrollable with Singulair alone, he decided to try taking one Zyrtec, thinking it might not hurt. Within 24 hours, the burping and throat swelling was back intensely.

The doctor switched him to Allegra. He took one and it helped him. He took a second pill two days later, and the burping reaction started. The allergist confirmed that people who have this "rare" reaction to Zyrtec may also have that reaction to Allegra.

If you are suffering from these symptoms, go off the Zyrtec as soon as you can. I wish someone had told us so that my husband would have saved himself a year of suffering.

Severe sore throats lasting 2-4 weeks, constant clearing of throat, constant burping (never had before using Advair)
