Hi everyone, I'm having a bit of a problem at night! I seem to be wetting very heavily during the night at the minute, and although I'm wearing plastic pants, I still seem to have trouble. The issue is, the women in my family have big thighs

I had to order a large to be big enough to fit around my thighs, but my issue is now at the waist. The waist isn't very fitted, and during the day this is generally okay, but the last couple of nights I've still woken up to a wet bed after having leaked at the waist. Does anyone know of a UK company where I could order a medium plastic pants but have a larger leg size? I did find one American company a few days ago, but can't remember the name of that one either. I'd prefer to order from the UK so they'd get here faster, but needs must!
On a side note, I am thinking about re-purposing a couple of old towels for tonight, with the hope that cloth nappies being bulkier it will make the plastic pants I've got a tighter fit. Any ideas on what *layers* I should use as a heavy night wetter? I have a mixture of towels I could cut up...
Thanks! Cheryl
