well I'm not so sure,
only from what other people who take it have told me!
I think it can effect memory in certain people, it effects people in different ways some don't have energy feel tired worn out all the time ect,,ect,, or just the reverse, but then agian this is something you really need to ask your Dr.
The stress your under could play a major major roll in how you feel and how the meds work, you need to let your Dr know your under stressful situations he/she maybe adjust your medcine accordingly/or change to some other meds...different dosage ect,,,ect,,
It can take a long time to get B.P.meds correct the way there suppose to work, a lot of it depends on each person and there health and the way you live.
Talk about memory loss, I ordered me some of that ''Focus Factor'' they advertise on late night TV...Nah'' that stuff don'r work....I forgot were I put it!..

nah just kiddin..
