I've been taking Levaquin for 7 days for a bad sinus infection. Last night I took the last pill. It worked very well, within 1 day my sinus infection felt a lot better. However it gave me severe stomach cramps, and it caused constipation and insomnia. And then I began noticing that I was getting some anxiety and depression symptoms which I attributed to possible PMS. However, now I'm thinking it's attributed to the Levaquin. I noticed that after taking it for 3 days I was feeling like I had to force myself to smile at things that normally would be humorous or fun. And for the last 4-5 days my kids and husband have been asking me if I was "sad" why I was angry so much. Today I thought maybe I should go see a counselor because maybe I am depressed. Then I thought to check on the side effects of Levaquin (I did not know there were even such bad side effects until I read this website). Well now I'm thinking maybe it isn't ME after all, but the Levaquin! Does anyone have any idea how long it takes for this to get out of your system? Are there ways to speed the process up? I have got to get this out of my system, I can't stand feeling like this.
