I have been on Toprol XL
50 for one year. Recently I have had a problem swallowing and
loss of appetite, All tests so far have come back negative, including blood, thyroid, diabetes, endoscopy etc. I have also had some lightheadeness, dizziness, weak feeling,shaking sometimes, feel like I am on a boat at times. I am doing best to eat more and have not lost anymore weight. I am just wondering can side effects appear after a year of none.
