I am on an antidepressant/effexor (not because of depression, but OCD.)  It is inhibiting my ability to lose weight quickly.  Does anyone know the rate it will take to loose weight in comparison to un-medicated people? 1/2 the time -1/4 the time- 3/4 the time?? (see, I am OCD)

I only eat 1200 cal. per day (vitamin FILLED foods only) I do exercise and burn at least 500 calories 4-5 days per week. 

It is pathetic that the drug companies do not disclose weight gain as a side effect.  It is a danger to one's health when BMI's are too high.   This increases chances of all kind's of diseases.    I NEVER would have taken effexor... If I had known this side effect. 

But anyway, my question....above, can anyone answer it?

I am 37 yrs. old and 5'1" and weigh 147 lbs.
