I've been taking melatonin the way Art suggested--2 hours before bed I take 1/3 total dose, then 1 hour before the next 1/3, then at bedtime the final 1/3.
I also take niacin, 100 mg, at bedtime since it helps also. So, most nights this really works and I fall asleep fast. I still wake several times per night but go right back to sleep. I wake up well and feel okay for several hours, then feel like I could nap but power through it since I'm at work.
I've been taking a total of 15 mg melatonin. But, like last night, nothing helped me sleep. I took another 5 mg melatonin an hour after bedtime and still didn't sleep but maybe 3 hours total. Any idea why? Or is this just something you have to deal with? (No choice there, I guess). Also, some days I get a real headache that lasts until noon or so. Is this the melatonin? I think so but it could be allergies.
Thanks, Art, this has worked more often than not and I'm happy for that.
