I think it's a good time to check if your pivots are still running smoothly if you are running a full suspension bike.
Also, try to do some subtle changes to your bike setup and see if you can get it better! Roll the handlebars slightly, try putting more/less spacers beneath your handlebar, move the seat a little forward, etc... If you find a more comfortable position, great! If you don't, go back and know that you have the bike set up perfectly. If you spend some time tweaking, it might prevent a more serious outbreak of upgraditis.
