Only a brief review of my history: I suffer from hyperhidrosis since puberty and especially under the armpits. I sweated through everything, whether T-shirt or a winter jacket and sweater underneath, whether in summer or freezing winter. Whether indoors or outdoors. The less pleasant, I felt, the more I was sweating too. That's why I could not go out with a t-shirt or a fitted shirt or I immediately had a bigger large sweat stain under the armpit decades. How embarrassing and uncomfortable to me was, everyone can imagine. And everyone who suffers from this unpleasant disease that knows something can lead gradually to social isolation after time. More than 12 years I suffered from this torment. No doctor could help me. I was sent with the comments as, "That's just in some way" home. At one fürchtbaren day, totally frustrated because of my problem, I have seen despair on the Internet for a solution. After a short search I found Yerka. There were different opinions on the product. By "not acting" and "it burns" to "it makes miracles" everything was in there. I threw something of whether there is a fire or not. I would even shake acid on my shoulder when I knew that they stop sweating. On the same evening I got myself Yerka and thus the healing of my fürchtbaren suffering. That was about 2 years ago. Since, by some miracle, I no longer sweat. Not at all. I can finally go with a T-shirt out, can without fear of my best things tightening that they are equal stained yellow and white. I can move my arms freely without fear that you may soon see my sopping armpit. Yerka gave me back the lost quality of life and for that I am him / her very grateful.
