I've tried all the remedies for this middle of the night wake up which leaves me zombie-like and grumpy the next day. I've had some success with herbal remedies - valerian, hops and passion flower tablets from Boots. But last night's red wine probably spoiled their effect. Could try the Paul McKenna hypnosis tape, I suppose. (You will follow the rules of sleep....). Hasn't worked for me as I don't follow the rules. No wine, no tea, no reading in bed - no fun.
One remedy that does work is Nytol - not the herbal one, the one you have to ask for at the pharmacy which is basically anti-histamine. The full dose of two tablets taken at bedtime does the trick. But then I wake up with a dry mouth feeling dreadful even after a full night's sleep. Even half a tablet works. Or a Piriton has the same effect.
I used to worry about not sleeping but recently have learned to live with it. More time for reading and middle of the night blogging. Off to bed to try some alternate nostril breathing now. Or other yoga relaxation techniques. More nonsense which doesn't work. Only an hour or so left before teenager starts banging around anyway. Takes her two hours to get ready for school. Madness. Like Macbeth I'll probably 'sleep no more' tonight. My 'ravell'd sleeve' will remain unknitted.
