How can I permanently get rid of my excessive mucus?

[Mucusboy]

I had a really bad chemical exposure when I was in college back in the 90s to Spray Mount. To this day I still have excessive mucus in my head, throat, etc. which I CANNOT swallow and CONSTANTLY HAVE TO SPIT IT OUT or it causes all sorts of breathing, bloating, gas pain, blockage in all lower body functions. I also have extreme sensitivity to chemicals. This is EXTREMELY Debilitating and played a part in breaking up my marriage as it's very noisy and GROSS. I've been to numerous allergists and taken allergy shots for at least 10 years. I went to another allergist who found a slightly deviated septum in my left nostril along with almost complete blockage shown with an expensive CAT scan about 5 years ago. The blockage was cleared with some strong antibiotics and I felt better for a little while but then the mucus production just really came on stronger than before. It's TAKEN OVER MY LIFE! I've even tried NATE, a procedure that's supposed to eliminate my allergies for good. This involved acupuncture and avoiding certain foods for a 25 hour period as a test. This was followed up at the next appointment by doing a strength test while holding certain vials that had what I was allergic to. It seemed to help some but ultimately was something I couldn't afford due to the frequency I had to go in order to get better faster. Anyway, if I don't spit it out when it comes up before, while eating and after then it really messes me up for the rest of the day. When it's really bad, I spit HUGE mucus bubbles into several paper towels which I have to carry with me everywhere. I have trouble burping and have to hit the areas on my body where the congestion is severe to help it go down. It's EXTREMELY GROSS and I've done well to hide it the best I can but I'm VERY self conscious about it. Every morning I have to excessively clear my throat very violently to get rid of the build up from overnight. I sleep with my head elevated on two thick Aller-ease brand pillows with 100% organic cotton pillow protectors that are FREE OF CHEMICALS. With all of this, I still don't sleep well and wake up tired and congested EVERY morning even if I go to bed earlier to try to get more sleep! To add even more pain to this, I have EXCESSIVE GAS and have to fart most of the day inconspicuously and mostly throughout the night. I also have to keep a cup by my bed, I have to have a cup at my desk AND in the car and constantly monitor and change/clean the cups to prevent a horrible smell! I'm going to try gargling salt water and putting hydrogen peroxide in my ears to break up the constant mucus.That said with all that I've tried, including asthma like inhalers, generic Mucinex now up to twice a day and especially before I go to sleep, I feel very sceptical that I'll get rid of it. It's a constant fight but I'm getting so TIRED of the annoyance and struggle. PLEASE HELP ME!!!
