Dilaudid 2mg?

Today I was prescribed Dilaudid 2mg for a previous back surgery (three in the past 4 years). I've had this administered through i.v while in the hospital, but this is my first script my doctor has given me to be taken orally. I have been on different pain meds in the past. As I am apprehensive about taking new medication i have never tooken before, i have discussed this with my dr. He went over everything with me. But just curious if anyone else has taken Dilaudid before in your own experience? How did it make you feel? Similar to Vicodin? Stronger? Weaker? I guess this is a morphine based med, right? Is this going make me feel "out of it" (ugh)?? Thanks in advance.
