Can i take melatonin or benadryl daily for severe insomnia? whats the highest dose of melatonin i can take. im exhausted. lack of sleep is a migraine trigger.

Melatonin: Generally Melatoin and Bendadryl are safe for sleep. The melatonin can be taken up to 10 mg at bedtime. In general, over 10 mg does not show any more benefit . However, most people get help with 2 mg to 5mg. I would look into why your are not sleeping. Anxiety, stimulants, hectic life style.
