I started 37.5 of venlafaxine (Effexor) 6 days ago. The first couple days I had the standard stomach issues/headache but for the past few days my anxiety has steadily been getting higher to the point I'm having to take extra Ativan which doesn't seem to be helping. I wake up shaking every morning, my anxiety is through the roof and I'm terrified. Im also having pains in both of my arms and feel rather weak. Should I stop taking this med or is this normal side effects that will get better?
