I am new to Atkins, just started last week. I am now taking 20mg/day of Celexa. Have just gone off of mood stabilizers that have caused 15 lb gain in 3 months. Hoping that low dose of Celexa won't make too much difference. So far weight has just stabilized, but I am going to be patient! I cannot go off anti-depressants. Interested in hearing from any other Celexa users.
