"i absolutely loved pristiq - great energy - great sex - felt good. i unfortunately suffered a side effect that i couldn&#039;t empty my bladder all the way. so that meant sleep deprivation. my md thought it was a uti, but getting off the medicine and seeing a urologist cleared up the symptoms. the urologist said it was a very common side effect of pristiq. he put me on flomax for a couple of weeks... loved pristiq, hate that i can&#039;t take it."
