Dexedrine
"Was on Dexedrine for 10 years. Loved it. Just stopped last month because I had tachycardia and an ectopic arrhythmia. Both started about 2 years ago, and I only recently had confirmed that both are non-existent when off of Dexedrine. Have been taking 30mg/day. Switching to Strattera tomorrow, hoping it can provide all the benefits of Dexedrine without the heart issues!"
