"i had gotten this medication after herniating a disc is my lower back. i only got minimal pain relief after taking 1 pill and decided to take 2 at night as the prescription states &quot;1 to 2 pills may be taken&quot;. i ended up with moderate - severe upper stomach pain and slight chest discomfort. i also noticed that as i would fall asleep, i would wake up suddenly with a feeling of having to catch my breath. this lasted for hours. it did however only slightly relieve my pain which is why i rated it 2 stars. i will not be taking this again."
