"prescribed instead of usual xanax for anxiety. 25mg, up to three times a day a day. not sure who could take more than one of these during the day. luckily i was at home and could take a nap. 2.5 hours later i woke up and was so groggy i could barely get out of bed. had work related dinner that i attended, went to bed directly following the dinner and slept until about 4am. still not what i would consider alert and functioning. i&#039;d rather have anxiety this stuff is not a substitute for xanax."
