From the age of about 60 I have suffered poor sleep.. And I know, speaking to my peers, that this situation is very common.
Very recently I have given up trying.. earlier to bed, no drinks apart from water after 9pm, no tech after 9pm, and a raft of other suggestions.. all ditched
Now I go to bed about 00;30 to 1am ( average, though some times gone 2am ), tea or coffee when I feel like it, doing various things on the tablet or computer and always reading my kindle for a while IN bed
Guess what ? I now turn the light out, go to sleep almost straight away, and do not wake up for 6 to 8 hours.. The bed does not look like a war zone in the morning and I do not feel the need to sleep for an hour mid afternoon, so I can only presume I am sleeping a whole lot better now
