I need suggestions! 
Since November I've been sick every day....No exaggeration, every single day due to a post nasal drip causing my throat to clog up during the night. It got to the stage in February when I started making myself vomit pre-breakfast so that I didn't have to throw my breakfast up! I've been to the docs, had blood tests, been given 3 different nasal sprays, varieties of allergy tablets and tablets which stop sickness. Nothing has helped!
When I'm in the house and yes, ONLY when I'm in my house do these allergies kick in. I'm forever, all day long walking back and forth to the toilet to spit, make that god awful noise clearing my nose and throat and when I cough a load of rubbish comes up! I've learned to live with it but it's killing me inside!
If it's only at happening home, what on earth could be causing it?
Dust? My room does get very dusty but my dusting routine is incredibly religious now.
Pets? I don't have any.
Smoke? No one smokes and I don't drink alcohol or do drugs either.
Plug-in Air freshener? I have since changed several times.
Shampoo/soap? The brand changes too regularly for it to be this.
Any other suggestions?
