In a small saucepan, combine the tart cherry juice, water, and chamomile tea. Heat over medium-low heat until steaming, about 5 minutes. Do not boil.
Remove from heat and stir in the almond milk, vanilla extract, and sea salt. If using honey or maple syrup, add it now and stir until dissolved.
If you used loose chamomile tea, strain the mixture through a fine-mesh sieve into a mug. If using tea bags, remove and discard them.
Pour into two mugs and serve warm. Sip slowly about 30-60 minutes before bedtime.
