Hallo. I have been on 75 mg Effexor for 15 months. It has given me my life back, so yes, it works! I have gone from sleeping only three or four hours a night with sleeping pills to sleeping for eight hours without sleeping pills. My anxiety has disappeared. I have gained 14 pounds in weight and I get "head sensations" but that is NOTHING to the anxiety I was experiencing. It takes about
four weeks to take effect but I would say it is worth a go.
