The health food store has other nut butters? Maybe your body wouldn't mind a different nut (which would have slightly different vitamins) Or maybe you could go "sideways" and add something like creamed peas (either "smashed" or added to your cottage cheese?), relatives to peanuts to your diet?

Can your doctor prescribe any liquid vitamins that you would then know might be effective for you?

Not what you have but that the Mayo Clinic is saying nutritional suppliments/liquid vitamins are good for troubles with digestion, etc. is worth knowing to me.
