I often found that small doses of Melatonin worked much better for me and didn't give me headaches the next day. I buy the smaller dose available (3mg at my store though some places have 1mg too). I split the 3mg into half. So I take around 1.5mg which works good enough for me. I also found the fancier "Melatonin Plus with L-Theanine and 5-HTP" to be not just expensive but also gave me severe headaches next day.
