Hi I have just been prescribed these for acid reflux but not sure if I have to take all the packet or just till the symptons have gone. Does anyone know? Also have been sent an appointment for an endoscopy . Am very worried about this especially as the appointment came through very quickly so am now thinking the worst even though I have been told it's because they've had lots of cancellations. Has anyone had one of these? Did you have sedation or just the throat spray? GP says it is not very pleasant so I'm guessing it is awful as they tend to play things down! Can anyone reassure me? Thanks.
