Hey dude! Yep I am lol. I think you should be good to get it done, but you need to start now. If they do what they did last year and allow medicals that were complete just without the SG signature, you should be good. That being said, get into your Flight Med ASAP. I know you're a shift worker as well so it can be a little hard, but just get in there and get your stuff started.
I needed a waiver and it took about 4 weeks on AD to get one. The SG signature while I was still in ROTC took like 2 months. Personally, I think if you start now you should be golden but you can't put it off any further. Lemme know if you need anything else!
