The reason I was a sking how long it stay in your system is bc it was making me feel VERY jittery and loopy headed. I was taking Tylenol Advil anything I could bc I had a headache that would not go away. I have put a call into my Dr. about this but in the meantime I was reading on the website about side effects and I have had several. I am on HCTZ for blood pressure, The first day I took the LEV. I was gassy, then my headaches got worse and I had an absoulte feeling of out of body. Like I could not function. I was sluggish and confused feeling and like I had too much cold medicine. No heart palpatations but just did not feel RIGHT. So after taking both my LEV and HCTZ for 5 days I decided not to take them for 1 day and the feeling went away for the most part. I now just have soreness in my left temple. Alsmost like tension. I guess after worrying all week im stressed. Any feedback you can give would be great. I wondered if I have like a residual headache and how long the med stays in your system.
