I wasn't sure where to post this (or IF to post it), but I think I'll do it here.
When I wrote to the FDA with my concerns, I asked if they would be so kind as to just confirm receipt of my correspondence. I'm aware that the process they are in the middle of right now is highly confidential; therefore, I did not ask them specific questions nor did I press for information.
Well, just this morning I got confirmation from the FDA.
So, at the very least, they received it, and SOMEONE read it. That's all I was asking for.
It doesn't even matter if it was an automatically generated "response" or not. It's confirmation.
And I thank them for that. My faith in the FDA has just grown a hair.
