A few brews and some chips will not de-rail you as long as you get back on track tomorrow. I having one now and going out with friends to eat Mexican. I know it's bad...but it's Saturday night and I WILL BE ON TRACK TOMORROW! For the past 6 months, I have been going for a jog every Sunday morning and helps me justify my Saturday night sins. I'm up to about 5 miles now and believe it or not, look forward to it all week.
Have a good weekend,

Picked up some whey today.The stuff ain't cheep !!
Will have to do some searching on creative mixing.Bought vanilla flavour as I figured it would mix better with a variety of choices.
Had 8 0z mixed with water and it wasn't as bad as I'm reading on the various forums.
I must say that it gave me a "full" feeling which is one of the reasons I chose to start using it..
