Happy birthday, Annie!
We use Clam magnesium in our house and it seems to do exactly what it says – makes us calm before bedtime (it also helps get the digestion moving, if you know what I mean – so be careful)! We usually put a teaspoon of the Calm in a cup, add a tiny bit of water (and watch the foaming). Once the volcano of foam stops, we add the rest of the hot water and enjoy it. We usually do it about 45 minutes before bed. I used to take melatonin on a regular basis, but the calm seems to do just as good of a job.
In a perfect world I’d skip the Calm tea and take a bath with epsom salts, but that rarely seems to happen.
As for other sleep tips, we try to limit screen time after dinner as a further way to wind down. It doesn’t always work, but I know we get a more restful night’s sleep if Im not checking the social feeds before bed (and work can wait until the morning). also, we keep our phones out of the bedroom and we invested in some blackout blinds (which are worth every penny).
Hope that helps! Have a great birthday.
