Well, I find adult conversation and persistence to work better than "going off on someone"
Make a list now... of each medicine you have tried, why you tried it, what dose, etc and what reactions you had. Do this now as memory fails on these things. I think anything you have now is more than you will later.
Your MD would have to be impressed with your diligence and sincerity in trying to find something you can take.
Here's a good link discussing medicinal allergies\

And again... I would demand BRAND names only if you have insurance, make sure the MD writes medically necessary on the top of the script or they won't pay for anything but generics.
good wishes
