Hi Princess Fi,
Melbourne IVF put you under completely as well. They only give you very light sedation and you wake up the minute they wheel you out.
They won't put you under if you only have one or two follies, but as soon as you have a few more, it's a bit stressful to the old body, and they will knock you out.
If you don't have a hot water bottle, or heat pack of some sort then you need to get one! The nurses always give me one as soon as i wake up, and it's a nice relief.

Good luck with the trigger. It's a bit harder than the normal jabs - but you will be fine.
Good Luck!!
