I noticed the change happening the following morning of my first dose. My singing voice, that is. I couldn't get the 'higher' registers to cooperate with me anymore. Then, a few days after that is when the growing pains started. My voice cracked pretty badly on the fourth day to the effect that it completely cut out on me mid-sentence and it took me a minute to get it to let me finish. In front of people... lol. That thankfully hasn't happened again.
I already have the tenor setting in (reverberates in my chest also) and yeah. Not painful anymore either (hot drinks really help with that - coffee most of all, surprisingly enough). Its settled down a fair bit but I don't expect that to remain for long (seems to want to go in cycles, most noticeably about a week into each of the doses). And my Adam's is quite more apparent (wasn't small to begin with, but it is definitely larger), despite my under-jaw concealing it most of the time (consequences of a Gene Simmon's tongue).
Only on my fourth shot as of yesterday.
So, right now, it seems I have two modes of volume at my disposal. Low and lower. It is exceptionally difficult for me to even raise my voice (I have never been able to 'scream' so...), and I can just forget about even trying to shout or yell. Not going to happen. I also cannot reach the same pitch level of most male singers on the higher notes either (which I had no problems with prior), but I expect that is due to the angle of my larynx shifting and the cords still thickening (don't think that will be a permanent change, I'll maybe get SOME of the higher volume and register back at some point). When I do attempt to get up there, it just fails on me. Not really in a 'crack', it just... cuts out.
