I'm 100% gluten free (celiac) and have found that it is easy if you eat at home and cook for yourself. If you have a family that is not gluten free or you eat out often, it is
extremely difficult. If you've got a gluten sensitivity, you'll find that increasingly smaller bits of gluten you ingest will cause you severe distress (gastrointestinal, migraines, general malaise, etc.) so it's a lifetime commitment.
I've lost a substantial amount of weight, too, in the 3 months that I've been strictly gluten free - mostly because I've been forced to be hyper aware of what I'm eating, and so it's easier to make good choices. I've read that if you eat like you're in the 19th century you can have a fairly healthy and gluten free diet (lean meats, fruits, vegetables, potatoes, rice, etc..)
However, like everyone else has said, if you don't have to give up gluten, don't! I miss bread
