Yeah it seems to me about half of the people (or more) seem to take the full 2 months to muscularly strengthen & relax into the new vocal fold dynamics. There is also a large amount of mind adaptation you must do in order to learn how to "relax" into it on top of the muscular aspect. I mean think about it: you are changing the fundamental physics of your vocal cords- this is something that rarely ever changes abruptly in a person's life. Everything has to change in order to become "good" at using them in their new different state. Just like switching from a tenor saxophone to an alto saxophone (which is one half register higher and has a slightly different embouchure/mouth position). Firstly it will take some time to learn the new embouchure in order to simply make a noise (relaxing), and secondly learning how to get the most musically out of a higher sounding register (adapting style).
As far as my own experience, there was a huge amount of adaptation involved during the part where muscles are changing to the new shape. I was up to the challenge though, whatever it took- I refused to get discouraged by a voice that wasn't acceptable to me. At first I experienced similar feelings with loss of range and worries about how my voice compared to other women. I channeled the stress/anxiety into an ongoing study into how I could make my voice better, and it still goes on today (I am still learning). I think I finally began to really relax about it around the 7-9 month mark, and now I am nearly almost completely relaxed about it (13 months post op). Things haven't changed much, except that I definitely have relaxed and I'm not pushing my voice to be somewhere specific- I just kind of flows in and out of higher and lower pitches. It varies wildly depending on the situation. Sometimes I use a very low voice at 170hz- especially if I have been talking a lot. I am still dealing with how to not tense up after long conversations. On the phone, my voice is much higher pitched ~230hz at times (but still depends on who I am talking to). When I talk to my mom on the phone my voice tenses again and I go down to 170-180hz (I do tend to talk a very long time with her though). It could also be due to the vocal tremor Dr. Kim was able to find with his super slow-mo laryngoscope camera (one side flaps slightly faster than the other making uneven closure). He said botox would help this, but the only injection I have had is a week after the procedure.
Just wanted people to know that I am still working through certain things, and is a constantly evolving process for me. If you don't like the sound of your voice after 2-3 months, you need to focus more on really getting your money's worth and learning to use your new instrument. You can't expect that it is some magical procedure that does all of the work for you, because it doesn't. Yeson just gives you the instrument, you still have to learn how to master it
I suspect this could take 2 years or more.
