living with sports supplements constantly

I am starting to think it is time for me to take my training to the next level and I am looking at loads of different options to help me out here. I currently cycle around 150 miles per week but I am not giving myself enough time to recover and my muscles are aching almost constantly. I am going to take the plunge into the world of sports supplements and try a whey protein and possibly a strong multi vitamin. I am not sure what I will do if this does not work, well I do, and I will have to cut down on my trainingL
