I used to take Toprol for blood pressure but stopped about 6 months ago under the direction of my doctor and after losing over 100 lbs. I discussed the possibility of that being an issue, but doc said if I was gonna have a problem stopping a medication, it wouldn't take 6 months. It would have happened immediately. All I take now is a multi-vitamin and an additional vitamin D supplement in the winter due to living where the sun never shines. No prescription meds at all.
