Susie Essman -- who plays Jeff's wife on "Curb Your Enthusiasm" -- tells TMZ, her expletive-riddled tirades on the show have consumed her life ... because now, she can't go anywhere without some crazy fan begging her to curse at them!!
Essman -- who is GREAT on the show -- was at Caroline's in NYC last night ... when we couldn't stop gushing about the most recent season of "Curb."
In fact, a lot of people are saying "Curb" has become a BETTER show than "Seinfeld" -- thoughts???
