I was pointed here by a fellow PN sufferer.

I started my lifestyle changes back the end of June. Since then I've lost about 18 pounds. I stopped taking Effexor XR which caused my weight gain in the first place. Actually, the Celexa I was on prior to the Effexor caused the majority of it. I came off the Celexa and had lost 30 pounds and my doctor put me on Effexor, which at the time I did need, and my weight shot up again though never as high as it got on the Celexa. I don't anymore. And the Effexor has also contributed to a major increase in my cholesterol. I refuse to take any drugs for that so I have to make diet and exercise do the job.

After coming off the Effexor and two other drugs the weight simply began coming off mostly on it's own. I am eating much healthier so I know that accounts for some of it too.
