Hi -
Alcohol can sometimes irritate your heart
and cause it to do unpleasant things. I don't know what your heart defects are, but drinking probably isn't the best thing to do. I know you want to have fun, and fit in, but if you do serious damage to your heart, that will not be much fun. I had to recently give up drinking wine due to arrhythmias, but I am hopeful that I will be able to drink it again. When you are older, you may not have the same reaction as now.
