Toprol-XL and sexual function

I'm a 40 year old male, diagnosed with high BP (148/110) and was placed on Cozaar (25). One month later placed on Toprol XL (25). Since then the side effects have been -
Sleepy (yawn, stretch, scratch, snore)
Loss of Mental Focus (I'm male, it was small enough before and now it's even smaller. The mental focus people...)
MUSCLE PAIN! Pecs, both sides but mostly the left. From deep muscle throbbing to pin-prick ouches. Left arm, follows the large bones (deep pain.) Lower back pain but hey, that may not be from the Toprol.
Oddly, sexual function has been helped. Sexual *drive* has gone down though. (Hey, my wife is 10 years older than me so she's ok) ;)

I hate this lethargic, crampy feeling. All my reading has shown to not quit Toprol cold-turkey but do a weekly dosage reduction down to 12.5 for two weeks before stopping. I'll see my doc in a couple of days to discuss this further.

Sidebar: EKG, Stress test show that my BP is reduced but not while exercising. So there's a fine line between side effects and prevention of High BP. Best of luck ladies and gents,
