Thanks for the advice guys, i'll definitely try the chewing gum trick! Anything that helps is worth trying!
I did think about doing AFF for ages, but here in UK its just so much more expensive to go down the AFF route, it works out being about $900 cheaper to go RAPS.
Im in no massive rush either, and i think it'll be easier to learn the skills with RAPS rather than AFF. I've still got a few weeks to go yet until ground school and my first RAPS jump. Im just hoping for good weather! (Something that is a rarity in the UK)
