As I sit here in the midst of gluten-free and Maybe gluten-free and of course the NGFs Products from our Pantry...I am ready to pull my hair out..my bf's older son (he doesn't live with us) has been diagnosed with Celiac last week...this is after being violently ill for well over a year...SO YES I AM VERY HAPPY THAT HE HAS FINALLY FOUND AN ANSWER!!!...knowing well from what I have been reading about this for months I do know that it won't magically be okay either...My Bf also a very good candidate for this, went and got tested for it (has not gotten results back) has decided with his younger son to go gluten-free for this weekend to see if it will help with their itching problem... ...I am trying to be supportive but for just the weekend???...I don't want to be the one to say a weekend isn't going to prove anything or maybe I'm wrong and it will...Do I start cleaning everything 1st or do I stay with the products 1st....all I do know is that I am trying to be supportive of this in every way...but I'm swimming here in a pool of Gluten and really now don't know where to start...Guess what I am looking for is some rational advice to get through this...or can someone tell how to proceed without stepping on his "Gluten Brain"...
