Sorry to read that you cant do CD.
SW and WW are both very good plans to follow, just depends on what you prefer.
I have done both in past (doing WW now to maintain) and I find counting my food in WW points easier and keeps me in control. I prefer the flexibility with WW too, so if I want a treat, if I point it and count it in, I know I can have it.
Good luck with which ever plan you decide to go.
