If you have slept poorly over years and decades as I have there is likely to be little belief that one little pill can make such a difference.
I have been on a 2 year journey with magnesium where I persevered for ages with the spray, made fitful progress it felt like 2 steps forward and one back and so changed to pills - for a long time taking 200 dose.
In the past month I changed to a pill of 500 mg citrate, and it has made a real difference to sleep patterns.
I frequently now get past 6am, on occasion 7am and incredibly on one occasion 7.50am - typically over many years I was up and about between 5.15 to 5.45 (best case) - a 7am waking up a near impossibility
I have no idea how long this will last and it may not work for anyone else but it is so dramatic that I felt duty bound to post on this thread
