I like your doctor's answer. I would be tempted to try them to see how they chemically help with your food.

I think we often see things as discreet items, a pill here, a meal there, and don't get that we are whole, not a collection of individual parts.

For example, I'm playing with my Vitamin D, my doctor prescribed it and monitors my level but I'm having side effects that I don't like (I keep accusing my husband of beating me in my sleep I ache so bad some mornings :-) I don't know what the answer is but I'm doing a bit of a lot of things to figure out what works best for me (sitting in the sun 15-20 minutes a day; may work in the summer but. . .).

Work with your doctor and psychiatrist and try something? Think up how long you would like the trial to last (3 months?) and get the specifics of what your doctor means by it working with your food, what food, what would he like or expect to "see" (I don't know if you are not eating enough or too much or what he is commenting on) and come up with a plan, your own personal scientific trial If you take control of the trials, decide what you would like to see and how you would like to conduct them, for how long, etc. you can get all the relevant information you want. I see my doctor every 3 months and am always conducting experiments in between to see how best to improve my health issues.
