Turning ad campaigns on and off at certain times of day

I’m getting the issue where my ad spend is being used up before the west cost of America even wakes up.

If I manually turn off the ads at night and turn them back on 12 hours later will that cause me any issues?

I can’t think of any myself, but I’m not sure if anyone else has had the same issue and if they used some other method to resolve it.

Anyone have any thoughts?
