Do I have to be careful for the rest of my life with my diet now?
Unfortunately, or forunately, depends on how you look at it, this may be your best bet.
I would ask myself, whats more brutal giving up this or that, or walking around with a "lighted lighter" up your butt feeling all the time.
Please littlebutterfly, I've been where you are. I loved certain foods, but they just kept giving me problems. It took me a long time before I finally said to hell with this pain, I'm cutting out this that and the other. And I finally won the battle.
Please keep trying, though surgery may help you, your still gonna wanna watch your food intake.
After conquering my fissures, there are some foods I would not dare eat like I did before. I may try em' once in a blue moon, but to eat them regularly like I did before would just make my old dormant fissures the happiest assassins alive.
Please do make a conscious effort to really watch what you eat. I know its hard for you, "butt" your "anus" will reward you for this.
HTH
P.S. It may be that Loving to eat and AF's go hand-in-hand
