This is great! I do something similar and find it very helpful.

Something that might be helpful, especially if walmart bothers you due to the chemicals found there, is to keep track of known chemical exposures. I sporadicallly keep track of things like the use of household cleaners, use of soaps/shampoos/lotion and other things I put on my skin. Some of these things effect my MG and I've had to make changes in what touches my skin and what I use to clean the house.

I like your list, it is well organized and should be helpful.
