I'm a 15 year old female with horrible insomnia and mental issues like depression/anxiety (just a few). I started off taking only 1mg of melatonin. I then increased to 3mg:nothing. I finally took 6mg:nothing! I took 10mg:still nothing! forcing myself asleep at 3:40, sometimes no sleep at all, to get up a 6 for school!! I don't even get the horrible side affects of taking 10 mg like people say you get. Why is it that 10mg doesn't do anything for me and should i ask my doctor about other meds?
