Have colonoscopy next month, morning appointment.Was told to take moviprep at 5 and 8 which means will likely be on the loo until midnight easily. I'm a real early bird, get up at 6 amd and bed for 9. Also take my utrogestan at 9pm I'd prefer to start taking the moviprep early in the day eg at 2 and 5 and be pretty much cleared out by bed time so utrogestan is absorbed correctly and I get a nights sleep. I'm very prone to insomnia, even when I miss a night so trying to avoid not sleeping that night if can. I can't see any reason why it's not possible. I'd only be drinking liquids anyway and would be stopping drinking at 8pm ish so if I'm cleared out,I'm cleared out, albeit a few hours earlier than advised? Anyone done similar? Ill ring them to check but afraid be just speaking to a receptionist who will advise sticking religiously to the instructions ,even if there's no real logic to them.
