Does sertraline have a peak time?

So I've been taking sertraline for three days now and I was just wondering is there certain times where the drug peaks because their is certain times during the day where my side affects are common on other times where its not bad at all

I believe it  is between 4 - 6 hours after your dose but that could be different for everyone. I have peaks and lows throughout the day. I think it goes that way until you level out.
