Strange time to be wide awake! Keppra?

Determined to lower these bloody epilepsy meds again! I always get the 'rare side effects'. I've finally snapped out of my zombie like state and it's 3:45am. 

It also appears to put me in extreme emotional states at times. I have a history of depression which I don't usually talk about but I think this contributes to me experiencing the mood disturbances that people can experience when taking Keppra. I take the unbranded type now because the government is trying to make cuts on NHS spending. I received a letter about this.
