I have been on Zoloft 25mg for 5 weeks for anxiety. I was still having anxiety and decided to go up slowly to 50mg. I've only been taking half (37.5) at a time for about 4 day's. I've been feeling more anxious in the first half of the day. Do I keep going forward and take the full 50mg? Is it common to still have some side effects when raising the dose? Or go back to 25mg for a while longer?
