So after two weeks the scar is okay:

My voice is not okay. Very thin, raspy voice. I felt that I have to speak different. It seems to me the "triple" changed a lot. With adapting the way I speak I am able to get something out every time I need my voice (my twins are 1,5yr old and I definitly need my voice!). I am still very quit and my pitch is very high. I did not made a measurement. I think it does not make any sense before I hit the four weeks mark. I know that I am not able to bring out any low noises. That is a result which I always wanted.
I have to return to work tomorrow. I still want to use my voice on rare occassions. My secretary has to speak for me

I did not contacted Dr. Haben. End of January I have an appointment with my ENT. Then I will see where I am standing regarding my voice. Currently I am not nervous. I know that my healing was good, I do not smoke nor drink alcohol. I drink a lot of hot camomille tea which always helps in short term. And I resumed sports. As far as I can say without side effects. So I have to wait, resume speech therapie and start Lax Vox again.
My only concern is my date next week. I hope I can at least say somethink, he is an interesting man.
