Don't know what was different but last night I went to bed at 10 read for a bit went to sleep and didn't wake up until nearly 8.30. I have been trying to figure out what I had done differently because instead of waking up tired I actually feel refreshed. The only thing that is different is I have started to use an Olbas nasal stick and had used it just before going to sleep. Have I maybe accidently found my own sleep aid I hope so!!
