I have taken Levaquin in the past with few side effects, dizzines...

I have taken Levaquin in the past with few side effects, dizziness, lack of concentration, it was for a UTI, so I drank more water than usual, and at 500 mg, I started to feel like it was just a little too strong after 2 days, then I cut it in half to 250 mg, and did pretty well. I recently, 10 months later was given Levaquin for a sinus infection, I have experienced several side effects at only 250 mg's. I took one at 8:30 AM and felt ok for the first couple of hours, then I started to urinate more and more, I felt like I had taken a diruetic and being as I am mildly dehydrated most of the time from not being able to drink enough fluids during the day as I have difficulty swallowing, this frighten me, I became weak, confused, cold sweats, dizziness, panic attack, felt faintness. I then decided to drink down some orange juice as I know how it feels when my potassium level drops, after the orange juice I felt somewhat better, so I truly believe the overproduction of urine and lack of adequate fliud intake caused my potassium to drop. My stomach is a little upset at the moment and I generally don't feel well, SO I would say, I will not be taking this drug again.
