I’ve already cut down on coffee, but noticed that my anxiety attacks are happening more and more often. I also get really claustrophobic and tense in weird situations, like waiting on a check-out line or when people stand too close. I’d prefer not to take a prescription pill for any of it, but may have to look into it in the future. Are there any suggestions to lessen the problem? Like, any herbal remedies, or breathing techniques, or dietary change? And is this common with others?
