@Wonk for me, sleep has always been a variable thing. You can get some prescription tablets. But, a couple of things from the chemist have also worked for me. Chemists Own Sleep Aid, or Phenergan, both available without prescription. A glass of milk can also help. I also try just to focus on my breath, in, out, in, out. All other thoughts are not necessary when I'm trying to sleep. If they are, then write them down, and try to move on, google those random thoughts tomorrow! I slept terrible in the hospital. If you have noise cancelling earphones, take them with you. I had ear plugs, but there was machine noise they didn't block out. What did work though, was I put the TV on the music channel, just focusing my mind on the music, rather than all the other thoughts, was helpful in getting some shut-eye. Best wishes to you in your journey. xx
