I forgot to mention my extreme sensitivity to cigarette smoke and sensitivity to candles burning. The perfume sensivity is particularly annoying since it means I need to avoid crowded indoor places. I might be feeling pretty good one day, then suddenly someone wearing cologne or perfume comes close to me and some of my muscles might start aching(or perhaps some might even start twitching?) and I might suddenly get a severe headache. Perfumes usually contain aldehydes, and those with a mercury and/or candida problem might not be able to properly deal with even a very small amount of inhaled aldehydes. The food sensivitvities are a big pain since the reaction may be delayed quite a bit, and it is difficult to figure out what caused it. I also wonder if it is a candida die off(which I guess is a good thing even if it is very uncomfortable) or if something else is going on. I like eating plenty of garlic and cayenne pepper(it helps with my sinus problems) but sometimes I have a strong reaction later(especially after eating garlic). Lately I don't have a problem after eating yogurt, but there was a time when I had a strong reaction after eating yogurt. Dental work scares me since I don't even know what is causing the nausea(The novacaine? The sulphite preservative in the novacaine? The mercury released during dental work? Chemicals the dentist uses? Inhaled mercury from just sitting in his office? cleaning agents used to clean the dental office(strong cleaning agents are used to disinfect dental treatment rooms).
