Started HCG once a week 2wks ago...SOOOO tired...

I got my 2nd weekly shot along w/ my T shot. I've noticed that since starting HCG I've been so tired(particularly getting out of bed in the morning). Nothing else has changed in my routine(sleep patterns, diet, workouts), and I can't think of anything else to attribute it to. The greatest indirect benefit of the T for me has been more energy(mostly as a result of much better sleep). It allows me to meet with a trainer 3x/wk. Anyone else have a similar experience?
