Metoprolol Tartrate and weight gain

So tired at the end of a day behind a desk, with normal walks during the day, To do anything at night. Sleep good 6 to 7 hrs not hungry at night eating habit is very good, alalchol use very little, but still weight gain

I've been taking Metoprolol for moderate high blood pressure since July2007.
I've been dealing with weight gain....nightmares....sleep disturbances and more within weeks since I began.
I wasn't sure what was going on with me.
I'm 55 and attributed all this to some sort of midlife crisis or something psychological.
I've contacted my primary care physician and will hopefully have an appointment within the next several days.
In the mean time I was told to STOP taking the medication and that he will assess my BP and alternative meds when we meet for my appointment.

Weight gain, general bodily aches and pains , anxiety/panic attacks/general depression, difficulty in concentration, loss of general interest.

I have been taking 300mg for 4 years. The first negative side effect was I passed out. The doctor reduced it to 225mg a day. I also take imdur, norvasc,lasex,altace and quite a few more. I am only 38 and I am surprised I don't have any more side effects. Oh I have experienced weight gain. Has anyone else noticed that? If curious I take all these meds for Hcm with ventricular tachycardia. Had an ICD put in in 2003. Man now that I type this all out sounds like I am in really bad shape. ok I am done babbling. To make a long story short I just want to know if anyone has had some weight gain?
