No appetite

I was diagnosed May 3rd via cat scan with diverticulitis (looks like in two places). My colonoscopy is scheduled for 7/25/11. Is this far enough out? I was on flagl for 10 days but still don't really have my appetite. A friend had told me it took a year to feel completely better for him. I just want to know if the appetite thing is normal.  I'm on a soft diet of fish and chicken, prune juice, mashed potatoes, sweet potatoes, canned carrots, cottage cheese, cheese slices, applesause, yogurt, tuna, eggs, carnation instant breakfast, cereal, steamed broccoli. Have not tried ANY Lettuce, hard vegetables, am petrified. Any other suggestions for food.
