Just a quick question... I have been on Zoloft 50 mg. and .25 mg Xanax for about 9 weeks. I take the Zoloft in the morning and the Xanax every 6 hours. Around 1:00 pm every afternoon I get so sleepy that I just want to lay down. Dose this happen to anybody else, and will it go away?? Any advice would be great!!
