I don't know if I'm necessarily hitting a wall, but my intake has gone down quite a bit over the past couple weeks.
One of the best things I ever did to reboot my interest in beer was joining Untappd. I used to only drink IPAs, stouts, porters, barleywines and the occasional pale ale. I had tried nearly every style, but I rarely drank anything other than a few styles. I downloaded the Untappd app and started trying to get every badge, and it really broke me out of my mold. Now I try all kinds of beer and have discovered or rediscovered tons of great beers that I wouldn't have otherwise.
I have had this issue before. I didn't drink any IPAs for a while because of it. And at one point I just wasn't buying beer because I didn't care anymore. Give it a little time and it'll come back. Craft beer is something I'm very passionate about so when I'm in, I'm IN and I tend to overload myself.
alternate with cider, wine or a liquor you enjoy for awhile. Perhaps even some sake! It's too bad there isn't a cider advocate site, as cider very closely follows beer on the list of alcohols I enjoy.
It's happened to me before. Luckily, it's only been temporary and I am good to go again in a few days or so.
Try ticking off some lists for fun, like drinking a beer from all 104 styles, or all 50 states, the top 100 lists, etc.
