I'm hoping to return to Ed Tech job at school Aug. 29th. I'm 11 weeks from ACDF and am worried whether in Aug. I can last a 7 hour work day. So i decided to practice a similar pattern now at home. I find that by 2PM my body wants to lie down to rest. I'm resisting and staying up until 3PM, which in September would be the end of the school day. Has anyone else tried this....I know I still have 3 weeks more of recovery time, so should I keep staying awake each day until 3PM or just give in for now and rest at 2PM? Thanks to all.
