I'm tired!!

Not being (particularly) sarcastic, but aren't you supposed to be exhausted at the end of a workout??

I couldn't say from the detail you give if 7 hours a night is enough, some people just don't need to sleep much and some people do.  I'm happy on 5 1/2 to 6.  I wake up naturally, so I use that as a marker, if my alarm clock starts waking me up as opposed to annoying me to get out of bed then I know I need some more sleep.

On the nutrition side (I'm guessing that as you're active already you know decent nutrition) make sure you eat straight after your workout, that's when your body most needs it.  It takes me 15mins to get home from the gym and I feel dreadfull for this time, but then I get in, rehydrate properly and grab some food (couple rounds of toast or a bagel) and feel much more awake for the rest of the evening/.

I was in the same boat about 2 weeks ago.  I eat right and sleep about 7-8 hrs per night. Anyway, enough of the boring stuff. I started taking a multi-B viatmin and L-Carnitine and it has helped immensley at gettting rid of my fatigue.

 7 hours of sleep on a training day might not be enough.  If you have the luxury of bumping it up to 8 hours consistently, try to do so.

Also, did you increase your caloric intake?  I have found that taking in the proper carb's prior to, during, and after training makes a huge difference in my energy level.  We use e-caps / hammer gel products and they have worked well for us.

Regarding your contacts and goggles, sounds like you need a new pair of goggles.  I have to wear contacts otherwise I'm blind as a bat - so leak-free goggles are a must.   I've read that when you are shopping for a new pair you should press them on to your face without having the strap behind  your head.   If the goggles stick to your face for a second before falling off, they are a good pair for you.  If they fall right off, they are not a good fit.  HTH.
