Girls, how did you cope with restless sleep? I fall asleep for a long time, then wake up often and can't fall back asleep afterwards. I have to go to the bathroom frequently at night. I get up in the morning feeling tired and nervous ?. It seems like nothing is bothering me that wouldn't make me want to sleep. I take magnesium V6 since week 5, 2 times a day. And I tried going for a walk before bed and going to bed earlier. Maybe something calming to drink at night. To the doctor on Friday to be checked out. But my nerves are already at the limit from lack of sleep.
