I have been taking these meds for 2 days now, and have some symptoms of side effects which aren't pleasant, but the one side effect which made me panicky tonight was that i felt my heart sort of flutter, but i checked my heartbeat and it was beating quite slow, which then made me panic, even though i was panicking my heart rate didnt really pick up, and its worrying me, i am only on 50mg the dr wanted to put me on 150mg but no way i want to take that much...Paul
