"first two days taking 50mg. first day taking i took relatively earlier so it would have time to kick in, without leaving me groggy, i felt it within a hour, and it increased by libido!! after two hours the drowsiness wore off, however i felt great and took a third of another to boost me back in a sedated sleep.  normally i have extremely long lasting visual dreams, but i never felt energized like i&#039;ve slept. this first morning i couldn&#039;t recall having a single dream and woke up relatively early, sleeping 8 hours. my side effects were feeling lightly hungover and numb until standing.  yes i couldn&#039;t breath out of my nose and yes my mouth became dry no matter the amount of water. 2nd night bad headache no sleep. will try 25mg tomorrow. not looking promising"
