Hi gang, First... If you wish to test your diet sensitivity to protein, just eat a Tuna Melt (tuna, cheese, etc. on a bun)... This I discovered (quite by accident) gives you about as much instant protein as anything I can think of, and if your meds are done in by protein this should give you a very graphic demonstration. As for peanut butter, sometimes it seems to cancel my meds, so I generally avoid it now. Second... I believe Vitamins C & E are important in how I feel, so I take both of these Vitamins every day (and have for years)! I also take a multi-vitamin once a day on the basis that it can't hurt & may help. I've tried other supplements with no visible benefit. all the best..................murray [log in to unmask]
