I also have sight problems and have tunnel vision, my mobility has been greatly affected by my weight, my driving licence was revoked due to my sight so being mobile is vital to me, it was really getting me down, I lost 11 stone a few years ago on lighterlife but ended up putting it all back on, I need to be able to get it off and keep it off. We will all get tgere and be so much helthier and happier, not long now till we are all on the loosers bench.
