Does anyone twitch when falling asleep. Then wake up

When I try to fall asleep absolutely bone tired, I have a twitchy jerky movement then I can't sleep. Does anyone else have this hateful horror going on. I want my life back!!

I do sometimes.To me calming tea or valeriane helps to fall sleep. 

I have had that all my life, long before anxiety. It always happens when I am completely exhausted. I believe it is over tense muscles quickly relaxing. Nothing to fear. Giggle about it and go back to sleep

Awww thanks for your kind comments xx

Yes, I get the same. I feel really peaceful then all of a sudden I get a huge twitch and it frightens the life out of me.  Then I can nod off for a couple of hours. x

Yes i get this all the time, like a twitch then a jolt, i used to get it when i was especially tired and knew it was a common thing to happen when someone is exhausted so it didn't worry me as much but since my anxiety got bad again i get it constantly when trying to sleep and because i am sensitive to everything it scares me now, i asked my doctor and she said it's part of the anxiety and exhaustion.
