depression
"I've tried many different medications over the years, and Pristiq has been the only one that I can seem to tolerate. I started on sample packs at 50 mg for a few months, and it was actually working, until my doctor's office conveniently ran out. I was forced to go on Effexor, and though it may be a similar drug, it is absolutely NOT the same. I felt shaky, agitated, and suicidal thoughts also came back while on it. 

Now finally back on Pristiq, and after two days, my anxiety/depression is almost completely gone. It's like some sort of "switch" went off in my brain. I don't feel desperate and I'm not texting someone 20 thousand times per day because I feel so suicidal and needy. I am a trashy mess without this drug."
