Hello dyemondgirl
This is Kitt and Welcome to HealingWell and the Depression forum. We are so glad you found us.
The AD's have been notorious for putting on weight. I believe there is another thread on here now that is about Lexapro too. You may want to browse that one.
Wellbutrin is the only med I know of from experience of friends that lost weight on that med. It may offset the Lexapro. I am on Cymbalta and I have gained. My Pdoc says it is because the med makes you hungry...........dah.
IMHO each person's metabolism reacts differently to the combo of meds. I am sure you will hear from other members.
Please keep on posting as the members here are wise and supportive.
Hugs
Kitt
