I have issues to sleep due to my job. I can choose any days I want work per week or whenever I want rest but the shift is 5pm to 3:30am. I get home by 4am. Eat shower then it’s 5am. Sleep til 6am. I can also work the morning shift. I tried that Thursday 6am to 4:30pm but went to work with no sleep. I slept til 9-10pm but woke up at 1:40am. Began cleaning til 5am. Left at 7am to wash car and do errands. Slept at 9-10am to 1:40pm. Left do do more errands. It’s 4am I’ve been in bed can’t sleep. I’m not yawning as I don’t feel super tired even tho I was super busy all day. I will work Sunday to Friday next wk. this week I didn’t work, which might explain why I can’t sleep. I have to see boyfriend by noon so my mind is too excited that I can’t sleep. I don't know what to do. I want sleep like before 10pm to 7am. Do I have insomia? Do I need take sleep metanol in?
