Ciprofloxacin for uti

I'm on ciprofloxacin for a uti. Today i started it and it says take it evenly because i have to take a pill in the morning and at night i took it at 9:25am , would i be able to take it at 7 or 8pm I'm very exhausted and don't think ill make it til 9; 25pm it's already been 9 hour's since i took the 1st pill.
