I have taken Zoloft for 11days, with a slow increase from 12.5 mg to .25 mg for the last 3 days. I feel my anxiety has increased, don't have the desire to do anything. I took xanax .25 mg last night and early this morning. Is taking xanax 3 x a day help me until I reach my theraputic level. My theraputic level is 50 mg which won't be for 2 weeks. Has any once else felt this way?
