No, the intense side effects went away for me pretty quickly. I remember the thirst too!! Ahh I remember it all so well. It's crazy!!! And the insomnia
I ended up getting my dose upped to 100mg, which is what I'm on now. I'm going to see my doc on Tuesday to talk about tapering off of pristiq. It did it's job for a few months, but now it's more harm than good.
I hope it works well for you, the side effects will go away soon. For me, the first two weeks were the best. I had energy, I was happy, I was getting along with my mom (never happens lol.)
