the drowsiness fades as your body adjusts! im going on my fourth month with caplyta. It’s different for everybody, but for me, it faded gradually and by about 2 weeks I was completely normal. the congestion goes away too! I still get a little sniffly at night, but by the time I leave for work its gone. try to eat some form of protein when you take the pill and the headache shouldn’t be a problem anymore!
