... feelings I should expect over the next few days. I have never been prescribed an anti-depressant before but I do take .25mg of Xanax every once and awhile to help with the anxiety. Should I expect more of a lethargic feeling or the opposite and does anyone know what type of role the Xanax will play in this. Note I take a very very small dosage of the Xanax and it is taken very rarely.
