hi. my name is retonia, which means rejoice and be happy. but i haven t been very happy lately because i ve been dealing with insomnia/anxiety and the dr. prescribed zanax, which i ve been taking for nearly three weeks--sometimes a whole pill and sometimes a half. a few nights i ve been able to fall asleep on my own but wake up after about 3-4 hours. what caused my problem? maybe the online book business i had when this condition came about. what worsened it was worrying during the day about whether i would sleep that night; i m past that now. just looking for answers. i m 5 4, weigh 137 pounds, walk twice a day and do weights at night, on a healthy diet which includes lots of greens, nuts, and fruit, not a diabetic and no hbp. can you help?
