Having a hard time staying asleep any suggestions? Melatonin makes me anxious....

Staying asleep. How long have you been struggling with this? Do you have any feeling of depression or anxiety? Do you know if you snore while sleeping? Do you wake up to urinate? There are many causes of frequent nocturnal awakenings. The best thing to do is to see a doctor who can sort things out for you. Avoid alcohol, caffeine, and exercise before bedtime.
Insomnia. Best approach is to find out the cause, for example eating late or alcohol or caffeine, medical issues or medications, and treating that.
