Fluid retention

So now I'm 3 weeks into the non-smoking business and its still going pretty tough and still not having fun yet. I don't know if anyone else has had this problem, but as well as all the other side effects like cravings and sleeping the day away, I've developed pretty severe fluid retention. Feet ankles legs all swollen and puffy, sometimes trouble breathing and thinking I might have to see my local quack and get some diuretics onto the job.
