Everyone is different.

Test E takes about 4 to 5 wks to kick in.

Probably just excitement at this early stage.

You will feel great on cycle, and then different mid cycle.IMO

Insomnia is common, BP up, acne, ect...

Then , your body gets used to it.

Sleep goes back to normal towards the end.

I would not worry about being cloudy minded.

You will feel moody during PCT though.

Best
