I do sometimes get anxious. Quitting caffeine and doing 10-20 minutes meditation everyday has helped my anxiety. Meditation has had a cumulative effect on my mental well-being. That is, the more time I spent meditating, the better I became at it and feel more at peace when compared to when I just started. Meditation also helped my sleep schedule which I believe helped with anxiety in turn. N=1 but may be it helps you too.
