Due to sleep pattern, can i take hydroxyzine (50mg/day) divided to 3 unequal doses; 2 day doses of 12.5mg every 6h followed by 25mg dose before sleep?

Sleep pattern?: Hydroxyzine may cause drowsiness for many hours and usually one would take a single dose at bedtime for this purpose. Depending on the person, some may get very drowsy with 12.5 mg others not even 100 mg. Are you thinking about sleep in 2-3 hrs cycle all through the day? Do realize it may impact your job and driving performance.
