A few years ago wife found out she has low bone density. Her doctor won't put her on a pain management plan fear of being addicted so she recommended sleep/pain pills that are bought over the counter. Wife started on tylenol that worked for a few months then just stopped. Wife woke up in the middle of night and could not go back to sleep back was off centered. Went to Excedrin and works good but found out that ADVIL WORKS BEST. Advil has not stopped working when Excedrin works most of the time but not always. Wife takes Excedrin in the morning every morning but Advil at night Not great stuff but does work most of the time.
