Does anyone else have trouble sleeping? I take ages to get to sleep and am very restless when asleep waking up a few time a night. I wear a Fitbit which records my sleep and I'm getting no more than 5 to 6 hours a night. I feel exhausted in the day. I work full time in an infant school and Tesco 2 evenings a week. I'm on 125mg of lethrothyroxine. I also take 10mg of amitroptline to help with sleep but it doesn't work that well.
