When I was in Bulgaria I had iron deficiency. So I decided to boil nettles into a tea. There is a difference between "Mitko Rouynekov architecture student boils nettles fresh from the garden" and a chemist makes nettles into a normal tea.
I try to improve my voice through hot and cold drinks but the words come out wrong sometimes. I really don't know what I should do.

@Yatsufusa Thank you for your reply but unfortunately I drank the entire cup in one sip. So I probably sound like a cow while giving birth. It's useless. A bully made me deaf, and I can't really make my own songs. There's technology.. you can sing along to music, but I really doubt I sound anything like Eric Englesias.
