I did. Surprisingly enough I did so before I even knew I had an illness so I can not tell you about it's effects on meds and so forth. However I know I started to physically feel better. I no longer have body aches like I used to and I am no longer almost constantly hungry.

I did not do this willingly. I want to say 95% of my diet was processed foods before meeting my GF. After moving in together my GF forbid me to eat processed foods anymore and started cooking for me from scratch. Her cooking is REALLY GOOD so my resistance died quickly. I hardly ever missed the processed stuff. I might get a craving for PizzaRolls, Doritos or other snacks on occasion but those times are few and far between.

One caveat: Mountain Dew is my one weakness. Nectar of the gods it is. Can't give it up.
