My Dr prescribed me Mirtazapine when I asked for an anti depressant, but after reading about metabolic changes, cravings, increased appetite and weight gain, I'm really not sure its the right choice for me. I've been struggling with depression since being diagnosed with a painful condition that's forced me to stop exercising. I LOVED running and working out, and without being able to I'm really struggling to stay happy, especially with the pain. I've already put on 14lb, which makes the depression worse. Can anyone recommend an anti depressant that won't cause weight gain? I think Doc chose Mirtazapine to help me sleep too, as pain can make that difficult. But honestly happy to use something else to help me sleep.
