Hi there.
I have also had these mini seizures, usually when I am passing from relaxation into sleep. It doesnt happen often and apparantly its supposed to be normal and harmless but i find it really scary.
I am at rock bottom at the minute because the insommia is so bad Im now getting 3 hours sleep 3 times a week and thats it. I cant function anymore , just feel so low.
I do hope you get better.
I have just read a report about electrode magnetive fields, these come from tvs, computers, anything electrical. Its supposed to mess up our melotonin levels and causes insommia for those suspectable to it.they recommened removing phones, tvs etc out of the bedroom and there are crystals that are supposed to be good at rebalancing your own energy.
At the moment i am willing to try anything but meds so if you come across anything that works please let me know x

May I recommend some meditation. Breathing in through your nose out through your mouth. Thinking to yourself as your about to rest..My head is asleep. My neck is asleep and as you think this relax those areas. Your arms are alseep relax your arms, breath. Do it all the way down to your feet and then try to sleep if it still fails try it again.

Wow I have just opened the Silenor link and am going to ask my doctor for some of these. Will let you know how it goes.

Thanks so much
