Struggling with Leaky Gut

Hey everyone, I am new to the forum and also to leaky gut. I figured out that I have it because I was referred to an allergist and he found that I'm allergic to beef, pork, eggs, milk, cashews, wheat, oats, corn, fish, shrimp, crab, soy beans, garlic, and a few other things that I'm certain that I've forgotten. I know for a fact that these aren't real allergies and must be sensitivities due to my lowered gut integrity. I've also been having signs of IBS that leans toward constipation, but mainly I want to stop the bad reactions I have after eating, which are mainly brain-fog, apathy, bloating, joint pain, gas, and severely dry eyes (potentially onset of sjogrens)

I'm starting to treat it myself, but I need help. Right now I'm eating the foods that I can eat, and limiting my sugar/carb intake because I doubt that I have candida, but want to be sure that I'm covering all sides of this condition.

So I'm avoiding the foods that I'm allergic to as best I can considering that not much is left to choose from. I usually alternate vegetables and have chicken on occasion, but since it's the only meat that I can eat I don't want to overdo it and become sensitive to it.

I'm also taking:
Diflucan (again to rule out candida)
Nexium (my GI said that I had too much stomach acid. I don't believe him, but either way I'm taking it to minimize sources of inflammation right now.)
Glutamine/Arginine mixture (inspired by Juven, but mixed myself, about 20g per day)

and of course drinking lots of water.
I mainly want to make sure that I'm doing everything right. It isn't getting worse but it hasn't gotten better yet, and I've been doing this for two weeks. I know it will take time, but don't want any of that time to be in vain. Tweet
