"we moved to va after 3 years on orders and my anxiety came back. my anxiety was situational. i had a refill left on my zoloft. i filled it but it didn&#039;t work like the first time. everything felt constricted. nothing seemed clear to me. i tried venlafaxine after crying to my doctor and i have been extremely happy. i will say, just like the other reviews mentioned, if you miss a dose, it&#039;s horrible. the dizziness, anxiety, foggy thoughts are severe. i&#039;m on 75 mg and feel great."
