"well i began the regular rx of pristique as samples, seemed to work great, went to fill the rx and insurance wouldn&#039;t covered it. so i guess venlafaxine is generic for this, however it is not at all like pristque. for a week and a half i had horrible i mean horrible nausea &amp; vomiting.... i tried to stick it out but i couldn&#039;t. in addition i also had chronic heat sweats/feeling flushed &amp; dozzy, diarrhea, and bad headaches! wait lets not forget, the libido was there, but all sensativity etc was gone out the window and ran down the street! this stuff was brutal &amp; i was miserable, i couldn&#039;t wait for the doc to say i could quit.... i just quit cold turkey cause anything would be better than that. definitely not a fan of these meds!"
