This is on the back of my MCS post about chemical fragrances and alcohol. I am an on-off smoker nowadays - I smoke when I get stressed out real bad by these DD's and their consequences on my life. I used to be a full-time smoker. So yesterday I smoked because of all this stuff with alcohol and fragrances bothering me heaps and noticed my MCS was better (except for the racing heart). I was researching why this might be online - well, I already knew cig smoke dulls the olfactory nerve response (the nerve in your nose that makes you smell things) but I also read that smoking dulls autoimmune responses too. I've been convinced that a lot of my problems are due to autoimmunity for a while as some bloodwork (ANA,RF,SED RATE) keep coming back high. Also just the symptoms I've had in recent years make me believe that anyway. I've always felt my immune system is attacking my nervous system. When I have a virus (in other words something else for my immune system to concentrate on) most all my symptoms lessen while I have the virus. Now, what I want to know but couldn't find an answer to is how do I achieve these dulling effects without having to smoke or get a virus??? Love Bunchy x PS Hope I haven't offended the non-smokers here as I understand this might be a bit controversial.
