Day one on paroxetine

So started taking paroxetine 20mg today. Took one this morning. It didn't have much affect until late afternoon evening, where I was violently sick and then again an hour or so later so that nothing is left inside of me. Also felt extremely anxious and horrible. I have heard with all drugs, especially this kind, it gets worse before it gets better so here's hoping and seeing how it is tomorrow. I will be taking a lower dosage tomorrow though. Think will take half, so 10mg, and see how that goes before upping it to 20mg.
