Can i eat prawns and oysters before a colonoscopy?

i am due to go for a colonoscopy in a weeks time and 3 days before i am due to have it i have a birthday party to go to on a seafood cruise.... i am seeking the opinions on other people that have had one or a docter that knows a little more............. i am supposed to be on a strict diet for 4 day before reducing the amount of food on a low fibre diet till basically i cant eat anything the day before my colonoscopy.. i wanted to know if it is safe to eat prawns and oysters and other seafood 3 days before having the colonoscopy? i dont need links to what i can eat before because i already have a list of things that would be best to eat but its only a small list.. seafood is what i am wanting to know if i can eat?
