It will get better, I can't stand most of the packs and only have chocolate and banana tetra's and peanut and cranberry bars, it was a nightmare at first, but once I figured out what I liked it was fine. I blend the tetras with ice and they are like a thickshake, gorgeous.
Also if you are really struggling, read through the SS+ literature, and if you do need something eat food off that list, rather than just going for the nearest thing. Perhaps do SS+ for a week until you have identified which CD meals you like.
Good luck
