I have been on Mirtazapine for about 6 years and it is magic in my view. I am on 15mg a day, taken about 9 pm, and it gives me a night's sleep - what could be better? Very dopey in the mornings but I'm retired so it doesn't matter. It did give me a huge appetite at first and I put on weight but I went to Slimming World and lost the weight. I now help out there which helps to keep it off. I do suffer with slow urination which I think is a side effect but it's not a major problem. Definitely the best anxiety drug I've ever taken. I hope to stay on it for life.
