I've been getting into herbal teas lately. Tons of chamomile and lavender to keep me calmer. I have a pitcher which I prepare a strong batch in and like to keep in the fridge for iced tea.
Edit: Some people will get super tired and fall straight asleep from the lavender.
We're glad to have awesome comrades here like you! I really liked your thread last night, it was insightful for me as a neurodiverse person going through changes.
