I have just had my EPU yesterday and can honestly say I too was sleepy throughout the stimming, kept thinking I was imagining it....
I would go with your Doc's recommendation and take the general for EPU, I am a scaredy cat (not from pain just from having to be awake to watch it)and would have demanded it anyway but as it turned out its the only way my clinic do it now....
I started Cetrotide on day 6 of Gonal F (CD7) and had it until CD 13, a couple of days longer than the doctor was counting on, only because my recommended EPU fell on a Saturday (hospital doesnt do day surgical procedures on the weekend) so they kept me going for another couple of days.
I was only going to take yesterday off (work is a bit busy at the moment) but felt alittle 'ordinary' last night after the anesthesia wore off that I decided to relent and take today off too.
Good Luck for your cycle
