I was doing great one year on antidepressants  (Prozac to be exact) and Buspar for anxiety and depression. Got my Prozac dosage increased to 40 mg mid year but after a full year I feel like the effects are it aren’t hitting like they used to. Im starting to feel even more anxious to the point where I’m clenching my teeth more, been feeling more depressed and just exhausted all the time. Is it time to switch to new antidepressants???
