Welcome Kev,
I too also have car nuts, and if I may give you some hard won advice, you're better off on a forum that specialises in chronic medical conditions rather than this one. There are some good ones about, but don't get mixed up with the animal ones, - following instructions sometimes turns out to involve a lot of guesswork.
I find that this time of year is the worst, it must be something to do with the temperature or humidity or something, I'm sitting here typing this with my ar*e in a bucket of WD40, and that bast*rd behind the counter at the chemist is just laughing all the way to the bank.
Good luck.
H
