I Typed My Questions And It Is No Longer Available??

I typed my questions and it is no longer available??
I am having oral surgery on 4/22. I am allergic to sulfites and want to know if there is something other than Novocain I can request. I do not want anesthesia.
Also, I am on medical marijuana for lower back, leg, and neck pain. From past experience, I am assuming that the day of surgery will be a high pain day since snow and rain are forecast. What are the drug interactions, and can I take my daily dose before surgery and after surgery? Is there a waiting time?
I already paid, but the previous question is no longer available.
