I've been taking 20mg since April, the side effects were pretty bad at first (it was mostly jaw clenching, sleeping a lot, depersonalisation and a lot of yawning) but they were almost completely gone after around 4 weeks. Doctors usually prefer to give the medication around 4 weeks before considering changing, unless the side effects are particularly bad.
When you say you don't feel like going out or talking to people, is it because you just don't want to or is it something like you're not enjoying it any more? Can I also ask what you're taking them for?
