I began taking this drug for a uti yesterday. After taking my fourth dose, I began experiencing a severe headache, nausea, cramping, uncontrollable shaking, complete loss of appetite, and the inevitable panic attack. My panic attack ended about 6 hours later. I was crying uncontrollably for atleast 2 of those hours. It was incredibly bizarre and like nothing I have ever experienced before. It is now 10pm, 8 hours since the last time I took the medicine and my mind is still racing and unsettled, but at least I don't feel as if I am not part of my body anymore. I would not recommend this medicine to anyone.
