Just had a few questions regarding training while on clen!

Heard from different sources that you can train much harder while others say its difficult to stay awake? Anyone with experience here?

Also I'll most likely run a 5/3/1 format, so just 4 core lifts and a few accessories with walking for an hour every morning? Keep lifting as heavy and possible? Would anyone suggest otherwise? Haven't really been able to find advice on both aspects.

Cheers!
