Metoprolol Tartrate and meds

MY 76 year old mother, on hbp meds for 30 years,METOPROLOL, for quite a few years now ,And she complains of severe pain in her shins, NIGHTMARES, for years now to her Dr. Lately she has been having fainting spells, and at times has short term memmory loss, The Dr did cut her metoprolol in half. dreams aren't as bad, She is going to have a D&C due to uterine polyop, all of this has sent me to the internet researching all the meds she is on, I feel bad I haven't done this research sooner, I just thought the doctors know???? Please we need to do our homework, research and take responsibility, for our health and those we Love.. I have been cooking and shopping for her past month, Lots of RAW fruits and vegetables,garlic and other healthy, herbs and oils, she has lost 10 lbs, bp has dropped 135/70 was 155/90 she is now down to 210 lbs, 5 ft, Im hoping the Dr. will take her off the metoprolol soon

They had me on a 600mg dose to begin with, which I cut way down to 200mg daily.I have high blood pressure and tachycardia and it does lower all that quite well. However, I am scared to go to bed at night, because I wake up shaking like I'm having seizures, I feel like my whole body is twitchy. Leg cramps, ringing in my ears, vomiting, nausea, dizziness, hot sweats, cold sweats, dark spots on the wall, (my blood pressure was normal), thirst, panic and anxiety, not caring about life or the house or bills, and horrible dreams, no appetite, then increased appetite, insomnia,and this all started about 3 days into the meds. Let your body adjust to it, yeah, it's getting worse so we'll see.

I'm taking 125 mgs. Metoprolol per day. I've been on that dosage for approximately one year for skipped heart beats (which were very scary). Now I'm hot. Constantly sweating. It's unbearable. I can't stand the heat! The only time I don't sweat is when I'm not moving. I didn't associate it with the Toprol until now. The doctor has been running tests for thyroid, infections, etc. But it doesn't feel like an infection. I'm just HOT. And after reading some of your side-effects, now I'm starting to put it all together. I've been going through some weird sleep problems that I've never in my life experienced. Never had a night I didn't sleep right through the night...until now. So to sum things up: sweating bad, sleep disturbances and slight depression.
