you are just naming random things. I have seasonal allergies I regularly take antihistamines, and Benadryl. No change. Acid reflux doesn't touch my lips nor do I get a sore throat from it.
No it doesn't help at all. If that is your issue, have you systematically done everything to see much one is causing your EC? Have you been cured after doing so? I have taken specific vitamins over a month no change. Not a vitamin deficiency. I regularly drink way over the amount of recommended water.
