My doc asked me (in my mid 70s) if I got up at night, and told me to take melatonin. Stuff works; I haven’t gotten up in the wee hours unable to sleep and unable to stay in bed since I started using it.Comes in 1,3, 5,and 10 mg; I started out at 1 and got as high as 5mg during the election. Thank God for that outcome.
Never had a feeling of being “drugged” by it, but had some occasions when I slept in a bit. Which never happened to me without it, since I’ve been retired. I used 2 last nite.
Years ago wife and I used melatonin, either 1 or 3 mg, and while it help as a sleep aid, It caused brain fog in both of us- unable to recall lifelong familiar words. Fortunately, temporary thing only.
