I am currently using a supplement that includes melatonin. It definitely helps....some nights more than others but a lot better than Tylenol PM which made me groggy in the mornings. I still seem to be able to work a full day and when I have headaches that won't go away I have to stay home. My HR dept is informing me that I only have 50 hours of FMLA time left. That's putting a lot of pressure on me too.
