Alkaline diet, MSM for arthritis

Hi! I'm new to curezone. I have really bad Arthritis in my knees. I read most of the stuff you recommended on the thread about free resources, and find it very interesting. I am taking MSM for about 4 months for joint pain at the recommended dose on the bottle with limited effect. Wondering if also doing the alkaline diet would help, and if anyone could give me personal experience with the alkaline diet and MSM? Should I be taking more?

I eat pretty crappy, always on the run, grabbing pizza or packaged junk. I know I need to eat more fresh food.

I like to hear other people's experiences more than what I read in books, on websites.
