melatonin

what is your opinion about taking 10 mg a day of melatonin for sleep. This is what my doctor recommended because I haven't been sleeping that well or is there another supplement I should be taking instead that can help me

I've tried using melatonin but it doesn't work good for me. It makes me more tired when I get up in the morning and also it doesn't help me fall asleep as well as I was hoping My insomnia has gotten worse as I've aged. Looking for any tips and it supplements that I can take to help
