the exhaustion is something i understand. about 5-6 years ago i had cancer. i used alternative treatments to heal. it was a full time job. when i was well, i continued my health education. i learned about dr wahls on bulletproofexec.com there, they have ideas for improving performance of everyone. since then i started using my own modified form of their bulletproof coffee and i've never had more energy and focus. with the information i found there, i've been, not only able to continue to be well, but to take things to a whole new level that i previously didn't know existed. i wish you all well. thank you.
