I've probably had enough of my Lomo Fisheye 2 camera after shooting 3 rolls, but here's a post before it goes
My experience with fisheye is similar - fun for a while, but not long. In the early 70s, Spiratone sold a front-of-lens fisheye attachment. Between my dad and I, we probably shot a roll or two's worth of pictures with it, then into the closet where it sat until 2010.
Fuji ST-701, 50mm lens with attachment, film type forgotten, maybe Plus-X
