I had 45 session..9 weeks.. drove myself..it is not a big deal but by week's end you may notice some fatigue...the radiation lasts maybe 10 minutes..you lie still..you hear some mechanical noises but usually they play music in background..they have you lower your pants and drape you will a towel or sheet..then ask you your birthdate to make sure they have the right program selected..then the machine slides you into place..day dream a bit and you are done..
oh gotta drink 5-8 glasses of water before hand and make sure you take a dump before hand..bladder full, bowels empty..
you will be done in no time.. good luck, skipper..!!
