I drink coffee and tea more for their beneficial phyto chemicals. If I were to stop them, I would lose this benefit. I limit it to a single cup of each.

B6 as P5P at 20 mg twice daily has helped my stress. Similarly, magnesium citrate has too. Theanine is also relevant at night.

I think the best cure for stress for someone who has saved up money is to quit their day job.
