I am EXACTLY like you!! but i work myself up for weeks till my appointment just for a check up....it got so bad that i all i did was obsess about going that i avoided it luckily i didn't have too many problems....first thing i did was find a good dentist...he almost makes my fear into a joke but doesn't mock me and understands completely!! my 2nd fear is the freezing. I have had 5 plus cavities done with NO novocaine and despite what one may think it isn't bad at all but thats just fillings 3rd i too am a pill freak, scared to try something that i may have a reaction too...until i found ativan! i have tried ativan, xanax and the one you take and by far ativan has helped the best with the dentist! i take 2.5 mg when i go but wouldn't take that much for anything else other than my visits. You can try yours if it works for you and 2 mg is fine...if i were you i would take something just to help ease the situation, also don't forget to tell them what you have taken and good luck, it is never as bad as we think it is going to be!
