I like the paranthesys from the point 5 and also the point 7 :))
When I was younger my parents used to give me medicine when I catched a cold or when I got a flu, but now I have tried a different approach. For a few years I haven't took any medicine for barely nothing and I must admit that I only catched a cold (or maybe it was a flu, who knows?) that only lasted for less than a week. I like to let my body fight itself with these kind of things because I think that it develops better antibodies and by now it really worked. Of course I rely on honey and C vitamin, tea and things like that, and this seems to be really well.
I don't remember to ever having laryngitis by now, but my girlfriend once had and I kept making fun of her. For a few days she had a man voice so I was calling her name only to hear her speaking and laugh. I was a little bit mean, but we had a lot of fun!
Hahah. That does sound funny. I hope I get my voice back to normal soon. For now, I'm just trying not to talk at all.
I really hope too that you will get your voice back soon, but from what I see in your post it looks like you are taking good care of you so I know you will recover fast!
