When to take Sertraline

I've been on sertraline now for 2 months, 100mg at the moment.  I am also taking propranol beta blocker. Both I take in the mornings.

I am plagued by constant tiredness and wondered whether taking the meds before bed would make a difference?

Hey! I tried morning evening and night. Night works the best for me but does disrupt my REM sleep a bit but means that i sleep through some of the side effects!
