I think stevia is okay, i've heard health freaks talking about supposed negative effects of sugar alcohol, but there isn't sufficient research on that issue. About your diet.
1. Eggs are perfectly fine and the best snack you can have if you're so low you're going crazy. Try to get organic if possible, but at least cage free with omega-3.
2. Be careful of ham, it often is laced with sugar, in fact I think pretty much all ham has sugar in it. Read the label. If it's a lunch meat, don't even touch it.
3. I think v8 is fine as well as tomoatoes as long as you stay in the carbohydrate level you've selected.
4. Everything else through the vinegar seems fine, some people have problems with vinegar (all types), but if it seems okay keep doing it. Apple cider vinegar is actually supposed to help with sugar control, so you can always try that if you want. Balsamic actually makes me gag.
5. Be careful of all milk products. If you seem okay with them, then go ahead, but they tend to spike sugar very quickly because they are basically a simple sugar. Milk especially, straight milk can cause severe reactions in some people within minutes. Also, there are all the problems with pasteurization and hormones and such, look into it, it will make you sick.
6. Not sure about cream cheese, read the label to make sure there's nothing in it that's on my list.
7. Everything else seems fine other than the tea. Be careful of the tea, if it's herbal with no caffeine or decaffinated, it's fine, otherwise do not drink it. Caffeine will cause a quick sugar crash, usually within minutes.
8. Water intake is fine, keep drinking!
