My doctor just prescribed me buspirone 7.5mg (1 and 1/2 5mg pills) 2x daily, and Xanax .5 mg as needed (I can only tolerate about a quarter of one of the Xanax if I wish to stay awake.) I am very underweight, (which we are also working on) so medications, particularly psychiatric meds, tend to hit me very hard. What should I expect the first time I take this buspirone? I am at home w/ 4 small children, so I need to know if I'm going to be too exhausted to function or something! Considering taking a smaller dose and building up to that in a couple weeks. Any advice is appreciated, as I'm extremely nervous.
