If it makes you sleepy, I'd take it in the evening with dinner. That way it will close to the same time every night and the sleepiness might not affect you as much during the day.
My meds did not change who I am. I did not become a different person. I am better off for my meds as they have only helped stabilize the moods. You went to see the doc for a reason and he/she saw you could benefit from them. It is worth a try but takes time to see any benefit; it also can always be stopped gradually if you don't like the effects. Stopping abruptly is never a good idea.
Also is there a close friend or family member that
you trust to talk to as you start this, just to help notice any changes?
Sending you best wishes.
