Well - at 85 I took the plunge with CPD because of endless night pains everywhere and total insomnia (some nights got 2 hours which was GREAT). First 24 hours seemed to knock me out - I slept for over an hour in the afternoon ! so I took fright and left it off for 24 hours. But now I think I am into a good routine, BUT, I find it extremely difficult to measure the drops into my mouth. So I just have to go by taste. I love the Gummies, which help in the early hours if I start to panic in wakefulness. I look forward to a future with less pain and enough sleep. The last time I had a good night's sleep was 02.09.1959 ! However there is one great UPSIDE - I have been dithery when in my garden for months - hanging onto twigs for balance - but in the last few days I am absolutely stable, which is terrific.
