62 year old male. After one month of taking it, my doctor raised me from 50 mg Metoprolol to 100 mg. No side effects until the dosage was raised. Then immediately got a traveling toothache, going from one tooth to another, culminating in an extreme earache. Had many of the symptoms mentioned in this forum, including short term memory loss resulting in my first auto accident in 40 years--a parking lot collision which was my fault. My doctor refused to ascribe any side effects to the drug except headache ; but I was told by local pharmacists that doubling the dose was too drastic and that my symptoms were typical. Had some rebound after stopping on my own a week ago, but pretty much back to normal, and the side effects are gone. I've tried other BP meds and am convinced that modern medicine just doesn't do it. Am looking into natural alternatives.
