I am 27, in fairly good health overall. I have had a very difficult year. I had a near-overdose on crystal meth in June which scared me. Afterward, I underwent many tests on my heart to make sure I had done no damage to it. I had numerous EKGs, chest x-rays, even an echocardiogram. They all came back normal. My question is, I have frequent almost daily palpitations. One doctor had me wear a 48-hour holter monitor, and I took a stress test. I am also now totally drug-free, and I avoid stimulants such as caffeine and alcohol completely. The palpitations just annoy me. Is this just something I am going to have to live with from now on? I started taking Magnesium, and also fish oil, but the palpitations continue. Am I making too much of having them on a daily basis, since all these tests came back normal?
