"i had such high hopes for this medication for my severe depression and anxiety. i was committed to try it for a full 4 weeks. i started on 10 mg and then went up to 15 mg. i never managed to get to the 20 mg due to overwhelming nausea, belching, excessive salivating, unbearable constipation and then the vomiting started. i didn&#039;t gain weight but that is because i couldn&#039;t eat. it did help with the depression but not the anxiety. definitely not for me!"
