Dose reduction can be tried.
Detailed Answer:
I read your question carefully and I understand your concern. Daytime drowsiness is a common effect of melatonin which seems to be your case.
Doses of melatonin are variable, they can go from 0.2 to 20mg a day. Naturally it is advisable to get the lowest possible dose which is efficacious. The right dose varies for each individual but the most common dose for insomnia is 3-5 mg.
So since you refer the above mentioned side effect I think you can try to reduce the dose to 3 mg a day and evaluate whether you'll be having the same beneficial effect with less daytime drowsiness. According to the noted results you can afterwards stay at that dose, further decrease it if still having side effects or return to 5mg in case insomnia worsens by the reduction.
I remain at your disposal for further questions.
