I decided it would be good to share this reader question and my answer with everyone.
Question: I have put on 2 stone and many inches around my abdomen since being prescribed lithium 10 years ago. I used to look "average slim" - small boned body. I have bipolar and was prescribed lithium 2 x 400 mg daily. I'm very happy apart from excess inches - HELP please!
Answer: I truly sympathize! From my starting weight I gained 80 pounds - about 5.7 stone - from various psychiatric medications....
