DOSAGE AMOUNTS AND TIMES? 47 yr old female 135 lbs trying to find the right dosage and when to take i have been on strattera and i notice a positive change. but seems to be getting weaker. have raised dosage to 36mg in the a.m and 18 in the afternoon, seems as though it is now making me feel sleepy! any suggestions? i would like to try taking it at night maybe but am afraid i will not sleep and i do not function well with out sleep. i also take alprazolam about .75mg a day as needed for anxiety. i really noticed a change and was very excited the first few weeks and am worried now it is just not working, if it is not why take it? any opions are appreciated! is it better to take it all at one time or split it into 2 doses?
