Waking Multiple Times a Night Since Starting HGH

Hey, Im experimenting with HGH, I took 2iu right before bed last night as I wanted to maximise the sleep recovery but instead I woke up around 4 times randomly, I must admit each time i woke up i felt good and not groggy but still, waking up multiple times is counter productive.

Has anyone else experienced sleep disturbances on HGH?

If i take during the daytime it has been making me feel sleepy so i thought id try before bed instead
