"i have been taking &quot;mirtazapine&quot; for 2 years. i was under weight with no appetite and was taking over the counter medicines to sleep. i was 40 years old weighing 89lbs before my doctor prescribe me this medicine - 2 years later i&#039;m 111 lbs and sleep well every night. this really worked for me i would recommend this if you need to gain weight (because it makes you hungry) and if you have trouble falling asleep and staying asleep."
