"i&#039;m only on day 2 so my opinion might not be worth much.  but here&#039;s how i feel:  i take the pill at 9:30pm, its somehow preventing the tylenol 3 i take for pain from working properly.  i feel really fresh in the morning, tired through the day and then ready to hit the bed at a normal time at night.  overall so far, i like it.  i don&#039;t have pmdd or pcos, my doctor had me on alesse because tri cyclen was causing me hives.  on the alesse i realize i felt really anxious and didn&#039;t even consider it was the pill until i took yaz.  now i feel kind of relaxed and not concerned about everything being perfectly clean.  i&#039;m also hoping for the weight loss and breast increase like others.  i&#039;m 5&quot;1 and just ballooned to 115lbs over summer bbq&#039;s."
