end of first week? Bro my only suggestion is that you FIGHT IT! Force yourself to go to the gym, eat, sleep, DO NOT SLIP UP. If you let the laziness get on top of you, your cycle will go to **** and you'll be very upset.

The lethargy kicked in for me about week 7 of a prop cycle. Its odd in my opinion that it is kicking in now. But I have never used halo so that could be it. Good luck, Stay motivated.
