Toprol-XL and moods

i am a 43 yr old male.........i was put on 100mg a day of metoprolol and it did the job of lowering my blood pressure and heart rate. however after about a year of taking the meto my orgasms would take anywhere from 1.5 to 2.5 hours to achieve. at first it was nice to go longer tham usual, but it has became a problem for myself and my wife. i sometimes think i will have a heart attack trying to release, we go thru bottles of lube to keep her from hurting, and my mood became very bad, i was looking for things to complain about, threatening people at work and so on. i started weening myself off meto 2 weeks ago my dividing the pills in half, and went to see my doctor this week. he prescribed lisinopril 10mg and had me divide my metoprolol in half again for another week. already my moods are 100% better, but i still have trouble achieving climax with sex in timely fashion. i hope that problem goes away soon. i am curious, am i the only male here having problems climaxing?

I have heart palpitations and was shocked back into sinus rhythmn via a cardio-vert procedure. I have been in regular rhythmn for over a year. However during this time my moods have become excessively black, my sleep has been irregular, and I can nod off at a moment's notice. During this time I have had lapses in short term memory and have suffered from bouts of bad judgement which I have never suffered from before in my life.

My cardio suggests keeping me on these but I feel I must get off of the medication. I have been off for up to three days and have found that my outlook and vitality has improved greatly.

I have been taking Toprol XL 50 since August 24,05.
For the past week, I do not have enough energy to take a shower hardly. I am so sleepy and drowsy that I almost fall asleep at my computer.
I am having chest pains, arm pains and my mouth has a horrible dry taste and I can't seem to get enough water. I have panic attacks and they are worse. I am easily depressed and my moods change quickly.
I love to walk but my legs feel like they are going to fall off now. I get what feels like restless leg syndrone when sitting with my feet up. I have to constantly rub them.
I have creepy feelings ( that is the only way I know to explain). If I could stop suddenly taking it, I would.
I plan to see a Cardiologist shortly. GP gave me the meds for high blood pressure.
