Yup, I've got a ridiculous flow (when it comes) and used a cup for my last two periods. I actually found it awesome, because now I can tell doctors almost exactly how much I've lost in mls, rather than how many pads I go through in an hour. I saw on Embarrassing Bodies that a normal flow is 60-70mls over the whole period, but I lose that each day for the first 4 or 5 days of mine. So now I get believed, yay!

Anyhoo, it is a bit annoying to empty the cup hourly, but I figure it's a lot less annoying than changing 3 pads an hour and getting blood all over my inside thighs and constantly smelling that ​smell. Can you buy some cloth pads so you're not wasting money by wearing a pad backup?
