Levinrec, in this other EKG-related thread (linked below), I passed along what my husband said about weed with verapamil. And then told you what's fairly common knowledge about weed strains and anxiety.

You didn't mention in that other thread that you were also diabetic and didn't list as many medicines as you do here. I agree with these others that you should probably be very cautious about what you add to that already significant drug cocktail you're on. In addition to causing possible complications with vaso-dilation and with anxiety, weed doesn't mix well with diabetes for lots of people and can cause fairly significant hypoglycemic response.
