I'm not sure exactly what you mean by thicker...
Just that the taste is getting to be too much? Too peppery kind of? You may need to cut the nic if this is the case. Bear in mind though that this may mean you need to step up your vaping amount to keep up with your body's nic needs.
Or is it a burnt or nasty taste? May be time to change your atty/carto/whatever you are using, or clean if appropriate. What are you vaping with?
Possibly the flavor of the juice is not what you thought it was a week ago. Welcome back, taste buds. It's been a while!

I had this happen with a couple of juices in my first few weeks. I had a cappuccino and a jolly rancher watermelon that I loved one day and hated the next. I couldn't even stand the smell of them any more. Maybe it's time to explore some new flavors.
If I haven't hit it yet, provide a bit more information and maybe we can figure it out.
I don't know if there is a specific forum like you mentioned, but feel free to post your thoughts, struggles, triumphs, and victories anywhere. There are a lot of people here, and whatever it is I'm sure someone can relate. I struggle with the analogs still, although I hesitate to use the word "struggle" because I did not enter this with an all-or-nothing attitude. In fact, all those bp NRTs do not allow this sort of attitude. And ya know, that is probably why I failed on
every single one of them. Multiple times. I bought my pv on a spur of the moment whim and decided if I want to smoke I'll smoke, but I'm gonna work on this vaping thing. And I think 6 packs of analogs in just shy of 2 months is pretty dang commendable, if I do say so myself.
ETA: I just reread your post and thought to add: You mentioned maybe not needing as much nic. That may be it, too. If you are really enjoying non stop vaping, like someone I know over here on this side of this laptop

, you could try dropping one level in the nic content. Or try vaping less, if that is how you feel like approaching it. That's one of the many great things about vaping- it is very customizable! (Yeah, I know that's not a word.)
