get a bottle of humanlog instead. or something faster. you don't have to use 10g per 1iu of slin, but its not a bad starting point. humalin is pretty long lasting, especially if you use it sub Q
If you wake up in the middle of the night to take a piss id use the GH than, it would be even better if it was towards the time to when you wake up.. (2-3hrs) and you wake up on a peak of GH rather the nothing. Waking up in the am is the lowest amount of natty production, hitting some EXO at this time is going to really change things up.
with what you have you should be killin it man, really killin in.
