I saw my medical doctor last month or so because I was having lots and lots of anxiety (mostly over difficult child and school, but also just in general). She increased my dosage of fluoxetine (prozac) and prescribed xanax .25 mg to take every 8 hours. I was taking it around noon and then at bedtime and it seemed to be working for me. I just started to notice I wasn't as anxious anymore. When I went back in for a follow up, she told me to only take it at night now and to go off of it. Why wouldn't she keep me on it if it was working? Is this not something you can take regularly?
