Hi! When I was on Depo Provera shots a few years ago, and also working in a toxic environment, I got gout also.
After stopping the Depo Provera shots and changing my job, it started to go away. Everyone told me to go to a doctor, but I didnt.
For some reason- I figured I should blend raw cranberries in a blender , mix with spring water and keep drinking a 32 oz's of it every day.
It helped me urinate alot and the gout went away even more til it was just a memory.
My guess is that gout is a symptom of a build up of toxins in the body-- even if it isnt just meat and cheese. It could even be environmental poisons over the years, or any toxin build-up.
