... taking them like a weeek after.I felt really bad, so I started taking them again on 4/12/13 I take 100mg every 8 hours for anxiety. I get blurred vision and sharp pain on the back of my neck.After I take my dose I get more anxiety, but after like 4-5 hours after taking it I feel great. Is that the med getting into my system the first 4-5 hours or the other way around?And I can not sleep!!!
