The best times I feel are:

7am,1-2pm and 10pm and later if you possibly can, i.e. just before you and your partner get into bed.  That is if your x3 a day dosing.  Half the time though, it has a lot to do with what you give and where you give it also though.  (Ideally at 2am if you do not mind getting up---give the smallest dose! )

I say that because studying the circadian variation and knowing how long it takes for hct to peak now, you need to take the hct at 7am as it peaks "normally" at 8am in a person with normal sleep patterns.
