hello
i have a scan in 2.5 weeks when i'll be 12.5 weeks. its at a different hospital to where i had ds1. this hospital has an old scanning machine, the type where you have to drink a pint and a half of water before the scan
to make it worse my appointment is at 8.30am, so they're asking me to drink this at 7am
i honestly don't know how im going to down that much water that early in the morning and keep it down and not throw it back up again. 
should i (try to )reschedule my appointment? i know its not guaranteed they'll have another date within the 11-13 week window.
a friend of mine (a trained dr but now a SAHM) sugested getting there at 8am and downing as much water as i can then. has anyone else done something similar?
please reassure me as right now i'm just feeling sick just thinking about it!
thanks!
