Thanks, TSM!

My affected tooth is in my lower jaw, so I guess that's good (I don't have to worry about the palate injection now, right?)
I wondered how the weed would affect anything. I told the Dentist that I am a heavy potsmoker at the initial appointment, so hopefully he will take that into consideration when evaluating my anesthesia dose. I don't know if I will be able to abstain for that long before but I'll try.
Also: he gave me Tylenol 3s at the initial appointment. Should I take those right before I go in, or the ibuprofen? Both?

Interesting on the tattoo/piercing factor too! I'm a big tattoo fan and plan on having a lot of work done this year. I'll keep that in mind for that too!!

Thank you to everybody for your kind advice!!
