Well, I hate the new site layout. It stinks as far as I'm concerned. I couldn't read the original post. It kept crashing on me, so I can only reply.
Everything is overwhelming if you are new to this. Don't feel bad if you miss something. Looking for the gluten free label is the best advice. Then you can at least clearly read the ingredients list. To begin with, I'd stick with whole grains such as brown rice, quinoa and organic corn products.
Everyone's taste buds are different. I can tell you that what I thought was gross when I first made the shift is not so now. I have, on rare occasions cheated a tiny bit on purpose. Wheat doesn't taste good anymore.
If you are an oat lover, get GF oats so you aren't getting any contamination. They are so good for you.
I still stress about eating out, but I decided I wasn't going to let my problem interfere with socializing. Most (and I do mean most) nonfast food places have a few things you can eat. At Olive Garden, for instance, they gave me my salad in a separate bowl with no croutons.
Take a deep breath and if you have an oops, unless it puts you in bed from complications, you'll remember it and learn from it. Each person's sensitivity is different.
God bless and keep smiling. You will find you feel so much better you'll not want to cheat!
