Your body is trying to keep up,too. You are doing it more harm than good if you don't have a plan.
Slow down and read up on the protocol or the order that you should do things in .
Get a handle on what you want to do and do one at a time, in the right process.
Read pasts posts here and on the many other forums on the site and you will find it quite benificial. Relax and don't do everything at once and you will feel better.
