I was suffering from anxiety and had a big presentation coming up at work. A friend recommended that I try something homeopathic and after doing some research decided on the Argentum Nitricum. The Boiron brand is what is carried at my local co-op, so I gave it a try. I was surprised by how effective it was after just a couple doses. I was noticably calmer, felt less stressed out, and able to prepare for and deliver my presentation with no problems. I would recommend this to anyone suffering from anxiety or performance-related issues. It's safe and I like the smart dispenser bottles with the twist tops, so that you don't have to touch any pellets you don't need to take at the time.
