I have the same problem and I was able to fix it and I am horrible at going back to sleep. Here are things that I found worked for me
- Try doing meditation if you can't fall back asleep right away. I would put relaxing music on and try to clear out my thoughts and eventually would drift off
- Wake up with less sleep. I know my body and if I try to do a WBTB with 6 hours of sleep it just won't happen
- Patience is key, once you master relaxing your body and mind you will be able to fall asleep faster and faster. If get frustrated because you can't sleep shake that feeling off and try to go back to being relaxed and don't give up
- If you still can't fall asleep and its been quite some time 30-60 minutes then just don't stress over it and read a book till youre tired or start your day and try again next time
