Thank you for your response and to everyone else, I think you are right I must have built up insulin resistance again and need to knock those carbs on the head, I walk a lot so think I am getting enough exercise, but got lulled into a false sense of security after losing the weight, I seemed to be able to eat what I wanted for quite a long time without gaining weight, and got into bad habits and then couldn't stop so even though I think what I am eating is okay, it just isn't and I am going to go back to no obvious carbs, eg bread, pasta, rice and replace or have something else.
Thanks Again, for the nudge I needed.
