I've been gluten free for almost 3 years now. It's hard. I wouldn't try to replace everything you eat with gluten free products because even though they are gluten free, it's still processed food. After a while of being gluten free, I realized that I also was reacting to xanthan gum which is in just about everything processed that is gluten free. It is very common to have issues with xanthan gum so keep that in the back of your mind.
Now, I bake with almond flour. It is expensive, but it's so much easier than trying to mix flours. There is nothing that replaces yeast bread (that I have found). I've learned to accept that. I do follow the Specific Carbohydrate Diet. It eliminates all grains and sugar (I use honey as a sweetener). I'm doing alot better with that. For some people, celiac (and tired adrenals) cause leaky gut syndrome which makes it hard to digest carbohydrates (other than fruits and veggies). So, you must heal the gut with foods it can digest. What you don't digest becomes a toxin.
Sorry to ramble. It's been such a journey for me and still is. I still am getting treated for my adrenals and chronic fatigue. There are some GREAT gluten free menus at many restaurant chains (Carraba's, Outback, PF Chang, Chili's, Pei Wei) and that helps when we are traveling. This is such a major life change. You must read every label. I found gluten in my mustard!!! My son who has celiac does okay with Betty Crocker Gluten Free mixes (like the brownies). Health food stores are a great place to find gluten free products and mixes. We have a gluten free toaster in our home and do not prepare gluten items though I do buy frozen pizza for the nonGF people in the family. Just keep asking questions if you need any help.
