I'm tired by 7pm, in bed by 8 or 8:30. Wake up consistently at 3 or 3:30 to pee. Then can't get back to sleep. Have to be out of bed by 5:30 for work. I'm nauseous 24/7 now but haven't had any actual vomiting yet (thankfully!) But I can't bear it with practically no sleep! My fitbit days I got 3 hours and 14 minutes last night. Not sure I'll make it through the day at work. Can't handle the emotions when I'm this tired either 😢😧😪
