So i started on sertraline about 4weeks back on 50mg. I take it at 9pm at night and my sleep has been ok no problems. My dosage was upped to 100mg a few days back and the last few days since upping it my sleep is interrupted, i feel im half and half the whole night like im tired but cant sleep. It was fine on the 50mg but since i upped dosage my sleep is interrupted. Will it ease out or shall i start taking it earlier than 9pm.
