Talk to ypur dr about how long before you start to feel better. If the answers aren't satisfactory, yuo have every right to ask (demand) a different medication or a different approach, perhaps another opinion.

i assume you mean that although you were depressed you didn't feel this bad before going on the paxil?? Am I right?? Many anti-depressnats do cause a lowering of sex drive, so you may have to accept that but only if the medications other affects in making you feel good are worth it!!!!
Had you been depressed for long? Do you think it's depression or stress, we know ourselves better than any dr & the treatment for the two is different????
