I’ve been taking Paxil 20mg for 2 weeks now, and tonight my legs have gotten so tense to where it feels funny walking on them and they get weak. My arms and fingers are tense to and I’m very anxious in my back and stomach.. I’ve thrown up tonight as well, first night this happens. I was on Lexapro 10 mg two weeks ago and my doctor took me off and started me on Paxil. Is this side effect normal? Really think I will call my doctor in the morning
