I've take Toperol XL the past several years now,,,, Don't let doctors or pharmacists tell you that generic meds are the same as prescribes meds, They just don't work as well,,, so I pay the extra 190 bucks a month to get the real deal meds instead and they work consistently well every time without all the strange side effects which generic meds do to me like someone choking me or my heart feeling like it's beating too slow during half the day,,,, It's all about disbursement. These are time released tabs and need to be consistant if they are to work well without side effects,,,I'm 55 and been taking PB meds several years now with success,,,, Not too many guys can say that,.... It helps having a pharmasist as a sibling...
