I am taking a tryciilyc anti depressant & am looking to loose weight, is this possible on this kind of drug?

Sure. It's definitely possible to lose weight even on a tricyclic, though it may be more difficult. Eat a healthy diet high in vegetables, fruit and fiber from whole grains and legumes. Limit/cut out all refined carbs (white flour and sugar). Exercise for 30 - 60 minutes 5 -6 days a week.
Definitely!!! May be slower, but higher lean proteins, 5-6 small meals a day, 80+ oz water and moderate increase in interval cardio nd resistance training should work just as well !
Possible. Weight loss is posible on any drug but requires reduction in caloric intake. Wt loss is not specifically associated with this drug.
