Gastrograffin

[Emeraldwaters]

Anyone know what's the quickest gastrograffin can work? Wonder if I will be able to go out for an hour or so a few hours after taking the first lot?

I'd be staying near my toilet, wouldn't risk going out!

Do you get much 'warning'?

I didn't get much warning. A lot of cramping literally just before I had to go!

Thanks!
