Elimination Diet or Virgin Diet?

I stopped artificial sweeteners a while ago...that is I thought I did but then when you look at some of the processed food ingredients and are shocked to find them hidden at the bottom of the ingredient list. Grrrrr. A food journal is a great idea! I need to start that asap! I should also look at a food elimination diet for migraines because I suffer terribly. I am going to a dietician on April 2nd (I just found out today). I struggle with my weight and I had to beg to see a dietician here. I asked for help with eating for FM and it was a no go with my doctor and honestly I had to BEG many times to see a dietician even though I have at least 50 pounds to lose which is not helping my overall health or my FM. My doctor says I should be able to do it on my own. I know that Cymbalta has a side effect of weight gain as well as Gabapentin. Anyways, I am so off topic. Thank you for your suggestions!
