How Should I Attempt A Gluten-Free Diet?

I have been informed that I might be allergic to wheat products and/or gluten intolerant. I’ve been advised to try and cut those products out of my diet.

I have had frequent stomach aches all my life and would like to try my best and see if this helps. I’ve never attempted a gluten-free diet, so if any of you have, please let me know what you did; such as preparing meals, and eating snacks, etc.

Thank you (:
