Patience and persistence is the key - and it is a hard key to find and use when things are as frustrating as being up ten pounds.

Some, maybe even most, of that ten pounds may well be nothing more than water retention related to quitting the smoking. If so, then it will probably correct itself over time.

You might, if you aren't already, try posting everything you eat in your journal here so that others can make suggestions.

I know you are in the candida thread and so I'm sure this has been suggested - but just in case it has gotten overlooked there is a notable section in DANDR specifically on candida and how to tackle it. Even if you've read it fairly recently, you might want to revisit it fairly often until you get that resolved.

Hang in there and Keep the Faith!
