Can you suggest something to drink for nerves? I recently took magnesium B6. There's a prescription drug, but I only take it in emergencies and not often, as it can be habit-forming. I need something mild and effective... My nerves are acting up, I'm sleeping very poorly, waking up several times a night, and I'm up by 5:20 AM... And it doesn't matter if I need to go to work or not. Today, for instance, I got up at 5 AM. Everyone else was still asleep, but I was up too. I've already been to the gas station, the store, and changed my son's bedding. I've started the laundry a few times; the machine is running... Meanwhile, my husband is still sleeping... I envy his nervous system 🤣
