Although the original Dr. Teal s Foaming Bath Soothe & Sleep variety is a solid option with its lavender scent and high-bubbling formula, I ve found the melatonin-infused alternative to be even better. The moment I pour the liquid into running water, it instantly fills the room with the strong but not overpowering aroma of chamomile, lavender, and patchouli. One big breath is enough to instantly relax me and set me into a sleepy state of mind. The formula creates more bubbles than others I ve tried, and they last pretty long, too. And though I tend to be quite generous with my pours, I ve hardly made a dent in the impressive 34-ounce bottle.
