Re: bad breath help
Get some Binaca spray and just do a quick squirt on your tongue if you think your breath smells bad.
Sounds to me like you also need to go to the dentist and get your teeth professionally cleaned, that will help a lot too. Everything that everyone posted is also a good idea, if it's possible for you.
I find that sometimes if I keep my mouth shut for long periods of time it will get dry and smell a bit, you should hit up the drinking fountains at school every once in a while just to keep your mouth from getting dry.
When all else fails...Ham Radio!
I still have the same old HP DV9700T laptop I've had for years...still kickin'
