Hi Mysti,
You poor thing, its so uncomfortable! Just dont do any "pushing" when you do go, it can bring on the roids!
Im lucky enough to not really have this problem, i go at least once a day however if i feel like i should or i havent been i have something that makes me go, like Mumintaz said, i know for me it can be a warm milo, fish $ chips (must be the oil!) or plenty of fruit.
HTH
