I first started taking venlafaxine 37.5 for two weeks. Experienced nausea symptoms, loss of appetite. I increased the dosage to 75 mg which I have been on for a little over 2 weeks. My doctor wants to increase me to 150 mg but I’m hesitant to do this because on the 75 mg dose I was very jittery and my heart was racing and I felt tingling in my arms and legs. I was actually feeling worse the second week taking it. My doctor told me this was my anxiety. I figured I would stay on the 75 mg dose for one more week and then try the 150 mg but I’m still hesitant. Do you get more side effects when you keep on increasing your dose or is this just my anxiety/panic attacks?
