"day 4 on phen, haven&#039;t lost 1 ounce! i know that&#039;s not a lot of time but i see most people lose right away. even if it&#039;s just water weight, i expected to lose at least a lb. it does do a great job at suppressing my appetite. maybe too good. i don&#039;t eat very much because i am just not hungry. hoping i see some results soon!! dry mouth is annoying and i am tired most of the day but awake at night."
