I just started using Natrol last night. In the 12 years that I've had CH, I rarely (maybe 2 or 3 times) have night attacks during a cycle. Well since Thursday night, I've been having two night attacks and one when I wake up in the morning. What a mess! O2 eliminated the night beasts within 15 minutes but I started the melatonin last night to see if I can avoid them all together. No luck last night, woke up 2 hours after going to bed with a Kip 9 that I'm still feeling this morning. I took 10 mg of Natrol last night with a 3mg of regular melatonin with it. I'll up that to 16mg tonight and see how it works. From experience I know not to expect 100% results the first night so I'll keep at it.

How many hours do you sleep? I get 6.5 on a good night. So I have to be bright eyed and bushy tailed at 4AM. I took 3mg of melatonin and thought I might be over doing it.

I typically sleep 6-7 hours a night, just the right amount for me to feel great in the morning.

I've noticed a few things since I started taking the melatonin this past Saturday:
1. Night CHs have stopped, but I do wake up with a heavy shadow that sometimes requires O2 or a good run to get rid of.
2. I dream like crazy. I dreamed a lot before, but these dreams are very vivid and I've had them every night.
3. I'm not having any CHs during the day, just a lite shadow or two.

Still can't figure why my CHs switched from day to night over the span of 24 hours, but I was able to combat them with the help of you guys. Thanks!

I've been using melatonin for a long time.  It has helped me much more than not.  I've become used to the vivid dreams at this point, they're normal.  I still use 3 mgs nightly as a sleep aid even when not in cycle.  It's one of the least "dangerous" options for us.  Strong coffee oftentimes kills the morning shadow.  I also use time-released with normal melatonin when in cycle, using 9-15mgs at about a 50/50 ratio. 
Glad to see others are finding relief with it.
