Hi Pat, sorry to hear that you're having so much trouble. I am grateful for the health care system up here, it is nice to not have to worry about money when going to the doctor. The wait times really depend on where you live, the city I'm in has a real problem with doctor shortages right now, so that's why it's so long. But other places aren't as bad. As for the sulphur connection, I'm really not sure...have you tried asking a pharmacist or looking the drug up online? Maybe you could find something there? I'm sure it's possible it could be affecting things, because many medicines do, but I haven't heard anything for sure. I hope you feel better soon! Kelly
