I have to admit that I have put on some weight recently. I am still taking 45mg mirtazapine and 1,000mg lithium. The annoying thing is that I lost it all once and now have about 1st to lose again. I have had my fair share of problems this year. Recently I have injured my back and also have a frozen shoulder which makes exercising difficult. I have had a look at the scales but not sure if I'm ready to do anything about it. EJ.
