"i waited to start until today, since i am off work today. i&#039;ve never been on a prescription before. (outside of antibiotics for cold, flu..etc.) i didn&#039;t feel anything until around an hour. my throat got extremely dry and i had an insatiable thirst. i drank glass after glass of water for at least two hours. (i also had to use the restroom every 10/15min, which is a concern for days i have to work. i drive long distances for work) at the second hour i had a crazy burst of energy and started deep cleaning my entire house. after i finished, i felt tired so i laid in my bed. i was in it for 30-45min, but could not go to sleep. i got up and ate two pizza slices, which is normal for me. i guess it takes a while before your appetite is suppressed."
