Welcome to NeuroTalk:

I really think you should try Kefir. This amazing probiotic liquid fermented drink (similar but better than yogurts) has 12 organisms in it and may help with some food intolerance.

It stabilizes things in the GI tract quickly. It can be a miracle of sorts. I get mine at Kroger's.

That said, your post is very interesting. You are highly motivated and working hard on your improvements. So congrats on that!

The egg thing may resolve with the Kefir. But if it does not, then I would avoid vaccines since they have egg protein contaminants in them. In fact vaccines may be responsible for later egg allergies IMO.

Fixing the GI tract may improve your glucose control too.

I find using slow carbs like lentils, black beans (red beans upset me), Edamame beans (soy) and peas give a slow control of
blood sugar and really stabilize after meal spikes and control hunger. I eat shrimp too at least once a week. There are some nice organic lentil canned products and soups if you don't want to cook your own. I often mix in broiled chicken breast to them, for an easy low carb meal. I personally like beets... so in moderation they can help satisfy...just not too much as they have sugar in them. The fiber in them slows the sugar absorption and beets have glycine in them which promote lowering homocysteine and provide the methyl group to SAM.

Nuts also keep blood sugars stable. I often just have nuts for lunch..either pistaschios, or simple peanuts. Almonds are high in magnesium but lately my teeth can't handle them like when I was younger...so I've had to do the peanuts. And smaller meals. A snack before bedtime if you retire late, like a Zone perfect bar or some cheese also helps nighttime glucose swings. Typically 1/2 Zone bar (I use the fruit ones as chocolate at night doesn't appeal to me) is often enough. Sometimes I'll have some Kefir. I mix 1/2 unflavored with 1/2 peach to keep the sugar down. I myself have a fructose problem, so I have to watch that or be cramping. Kefir is very satisfying. A friend clued me in on it in Sept, when I was having mega GI agonies this past fall. Now both hubby and I are using it!

Eating high protein breakfasts are good too. I have left over chicken, or steak with a little bread (which I know you can't do), but sometimes mix in the beans with it. Not typical breakfast fare, but one gets used to it. I get the low sodium Bush black beans in a can.

A supplement to try is R-lipoic acid (stabilized form which is new) and at 100mg a day, it also stabilizes blood sugars.
Many of us are using this now, Doctor's Best brand is affordable and easily purchased on Amazon now! Also at iherb.com
This really helps with PN as well.

Watch out for MSG... as it is very bad for PN and pain in general.

I did GF for 3 yrs and it really didn't help me. But avoiding fructose is a huge improvement. I am also sensitive to nightshade veggies, esp potatoes. So I keep tomato very low and avoid potatoes now. I can tolerate some tomato, and use mild salsas sometimes mixed with the beans. But I have to watch that and not do it every day. There is a nice mango salsa at Costco that works for me. There is an alkaloid in potato called solanine which is now thought to be cumulative in the body and not removed...growing more toxic by the day! I got rid of alot of foot burning by avoiding potatoes. Hot peppers also can bother me as they are nightshades too.

So those are some of my tricks. But yes, variety can be lacking!
