Glad to hear its working out. Just keep doing the lip trills and drinking pleanty of water and you'll be fine. A few weeks ago I strained while I was recording some stuff for about 6 hours with about 2 hours of sleep and because I did everything I suggested to you my voice was back to normal in two days. If you can get some at a GNC or something, get some Throat Coat Tea. It takes a bit to get used to because its pretty bad but have a cup of that every once in a while with some honey in it and it helps too.
