Thanks everyone.

Poor mans doping ... sure ... I don't have a problem with that. I want to feel and do as best I can and if it means getting a little help, I'm open to it. I guess I'm looking to feel healthy and energized and have read that B12 can help with allergies as well.

I may give my doctor a call. I think that its good to take a vitamin, and will start with a multi in the morning. I did pick up the B12 drops - everything I've read says it can't hurt you - so I'll give it a try.

NY biker - we do 80 this weekend and the Century isn't until the 23rd - I think that's 2 weeks? I trust my coach - so I hope it will be okay- I'm quite nervous since I had to sag last weekend and missed riding the 75 mile ride! I'm very new to cycling. This is my first time riding and joining Team in Training has been a great introduction to the sport.
