I need help

in 2 weeks I have to go for a trans oesphogal echo - where they put an ultrasound probe down your throat to look at your heart.

I have cancelled once already - and i want to cancel again.

Im so scared of the sedation, worried that I wont wake up. Sedation is a must for this test apparently so that I am not asleep but i wont remember anything

My HA is kicking in big style and I dont know what to do.

What does the sedation feel like.

Any help/advice would be greatly appreciated

Amanda
