I saw Dr. Kalidas in February of 2010. Based on test results, he told me to completely cut out gluten (not just cut back on it). I had cut it back before but not noticed a difference. I thought it would be impossible to cut it out completely. But on the doctor's orders I did, and about 1 week later I woke up and wondered what in the world was going on and why I felt so good. It had been probably 7 years since I felt so good.
Some of the symptoms I had been experiencing were severe depression, sadness, headaches every day, sometimes migraine headaches, extreme fatigue, skin problems, irritability... etc. I was shocked that cutting gluten out of my diet practically eliminated those things, and that what I was eating could affect my mood so drastically.
I'm on a tight budget - I don't buy many of the ""gluten-free"" foods, because they tend to be more expensive. Instead, I just have more veggies, fruit, rice, beans, potatoes, meats, and nuts.
I didn't notice a difference in how I felt for over a week, but then it was like a switch was flipped and I felt amazing. It was so strange to feel happy again. I still have to be very careful not to have any gluten (even having a pill that had wheat starch in it made all my symptoms come back for three days).
If the doctor suggests going gluten-free, give it a try. You could have your life back!
