I use to take 2 Advil every day before my workout for years, I found about 8 years ago that my kidneys values were down significantly (also due to high BP), my doctor put me on tramadol which is a mild narcotic but is better for the kidneys. I take it sparingly but it is getting harder to get as doctors are reluctant to prescribe opiates anymore. I do get it but instead of using the 4/day they prescribe, I take 1 or 2.
