How long did it take for the back pain to subside? I recently tried 5 mg Ceebis and had to stop after day #3 due to the low back pain. It seemed to emanate from my hips up to the lower back and even down my legs a bit. It was so bad I was unable to sleep, so I stopped and after a day or so the pain subsided.
Took me about 10 days for the back pain to go away on 5mg per day dosage
