I did not have my prescribed pills on me yesterday but luckily my friend had a V 2090 xanex. I had never seen this imprint before so of course I questioned it. My friend said it was simply generic and that there was no difference in between it and my normal 2mg xanex pill. I do not know if it was me over thinking it or not but I felt like it did not have the same effect on me. Are these any weaker? What is the difference between the two if any?
