I'd been taking Melatonin 3mg sub-lingual for a few weeks to see if it helped with my poor sleep, and found that it didn't make any difference.
Changed to 10mg capsules a week ago, and I think I'm sleeping a bit better. Still wake a lot but soon doze off again. On two occasions I've still been unable to sleep, so have taken a second Melatonin.
The interesting thing is that on both of the following days, I didn't have my usual waking sore neck/ headache, and was able to go until nearly 1pm before needing to medicate.
This is most unusual as I generally have to take something either first thing or mid morning, and even then can't function.
On my two good mornings I've able to do a few things that were not possible with my usual sore head.
I'll do a trial now to see if in fact the Melatonin is having this positive effect.
Have read a bit about it and there are studies which have indicated it can help with migraines and cluster headaches.
Fingers crossed!
