In brief, I've suffered postnatal depression and have been on 40mg Citalopram for 18months. I've gained a hell of a lot of weight, due to numerous factors and have now gotten my head into the right place to shift some timber. I want to do Slim Fast for two or three weeks to kick start my diet but before I do, does anybody know if it's safe to take citalopram and use slim fast at the same time? Last thing I want to do is unravel. Google hasn't been very helpful thus far.
