Hi AI3x, I hope you have managed to get some more sleep last night. I had a similar unpleasant experience trying to grab some sleep. A few points on reflection:
1) I normally sleep on my side. On my side, I don’t snore. However, I think that I snore/airway obstructs when sleeping on my back or sitting up.
2) My Cardiothoracic team told me to avoid sleeping on my side for 4 weeks. Other people who have been to different institutions within the same city, have been told that they can sleep on their side if they wish. I found sleeping on my side too painful but some other people have no trouble sleeping on their side early after the surgery. I concluded that you can sleep in any position that works for you - there are no definite rules.
3) Sleeping with one side partially propped up helped me.
4) When I woke up, which was generally after only 1 hour
, I found it useful to get up, stretch, reposition, take simple pain relief, before trying to sleep again. Just lying there rarely worked for me.
5) The disordered sleep may not just be about the pain/discomfort. I remember having unpleasant dreams/sleep hallucinations. Opioids improved my comfort but increased these dreams. Overall, I found opioids not particularly helpful so I completely stopped them within 1 week of the surgery. These funny dreams settled after a couple weeks.
6) It will improve. At about week 4 to 5, I felt that my sternum had solidified. Sleeping became drastically easier, including sleeping on my full side.
7) Accept that sleep will be fragmented. Humans can survive with fragmented sleep (but be disgruntled) - ask any mother of a newborn.
You are not alone in finding sleep challenging after surgery. I feel that it is the hidden, biggest challenge of cardiac surgery. It will improve. Hopefully some other members will post their golden tips to help. Best wishes
