Well....the REO is a little hard to get because they stay sold out. You're getting your post count up, so after the forum cycles through it's reset, you'll be able to go post on the REOs Mods sub-forum. You will get a LOT of information there....just jump in and say you're thinking of buying a REO Grand and many, many people will chat with you about getting one.
One more thing to mention....and it's just a thought....but I've seen it happen time and time again. There is something that seems to happen at around the 2-3 week mark. I don't know if it's real or psychological....but people say they can't seem to get any flavor, they can't get the good vapor anymore, their pv's not working right, the juice tastes funny....etc. It usually passes in a day or two. Like I said, I don't know what it is, but there are whole threads about it....
So, you could just be having a bad vape day.

Maybe switch up your juice or something. How much VG does your juice have? What nicotine level do you vape? Do you use carts or are you dripping?
