About "natural remedies", the main thing I found to be both efficient, legal, non-addictive and reasonably cheap is kava. It helps with anxiety, and also makes me less socially inhibited and somehow help with social skills, it does not make my personality change unlike most prescription or recreative drugs (benzos, alcool, cannabis), and the impact on wakefulness and activity is marginal with reasonable doses (although higher dosages will make you sleep).
Sauna sessions help me a lot, too. I love the feeling of diffuse heat getting into my skin, and it also relaxes my body which in turn relaxes my mind. (It also helps with my back pain problems.)
