    Reviewed Pristiqon 8/28/2015Avoid withdrawal at ALL COSTS. Vivid nightmares, migraines and insane mood swings. I take 100mg 1x 24/7 with buspirone. It was effective in the beginning, but has tapered off. I would suggest another medication before this one.

    Reviewed Pristiqon 3/22/2017Alcohol definitely has a stronger effect on this medication. I am usually pretty warm compared to before I started this medication and sweating happens relatively easy. Occasionally, I feel jittery, get hot flashes, or have ringing in my ears. I also noticed I yawn more during physical activity.

    Reviewed Pristiqon 12/28/2016Definitely take in the morning. I had no drowsiness, but rather felt more alert. I couldn't sleep when taken in the evening. Uptake is practically nonexistent with 50mg being both a starting and therapeutic dose. Took about a week and half for noticeable change. Within a month, great benefit along side psychological talk therapy.

    Reviewed Pristiqon 10/7/2016Although this is supposed to be weight neutral I gained 15lbs in 4 months. I was constantly hungry and bloated. Some of this could have been due to the Extreme APATHY I encountered on this medicine. It reduced the extreme anxiety encountered while being unemployed and I can say it did help turn that around, but almost to an extreme point of apathetic procrastination & Fatigue.
