After my first implant, I'll never do it again without lido. Ice numbing led to a long night, and may have contributed to a not-deep-enough pocket leading to rejection. Pain is quite real. This time around, I asked my dentist for some, and he just gave it to me. Needles and sterile syringes can be bought on ebay (not at stores I've tried for...legal reasons? Pharmacies require rx)
Also, your dog looks like my dog :).
Heh, I'll tell you, I must not have been doing it right, then. It's not the cut that gets you, it's digging the pocket.
No, I don't know him particularly well, though I've known him for a long time. I told him I was putting together an emergency first aid kit due to being involved in a lot of community service activities (which was true). Lidocaine does require a prescription to buy, but it's not heavily regulated either. Low capacity for abuse, low risk.
