Zocor and heart palpitations

Heart palpitations, erratic heartbeat. Discontinued both drugs

I had been taking Zocor for 10 days when I woke up in the night with heart palpitations, wobbly legs, a severe headache and dizziness. Shortly afterwards, my legs began to twitch on their own and cramped up. This happened several nights in a row. Then the twitching spread into my arms and neck. My muscles became very sore, then weak to the point where I couldn't stand up long enough to take a shower or get out of bed without help. Thankfully after being off of Zocor for 3 weeks I am getting some of my strength back, but I am plagued with a constant headache and dizziness, sometimes nausea and vomiting. Tests for muscle enzymes, liver damage, etc. have all come back with normal results. I am 21 years old and Zocor has made me feel about 75. Like others on this site my doctor did not think the problems had anything to do with the Zocor, but helpfully suggested I try incorporating more fat into my diet.

Can anyone tell me from experience how long I can expect these side effects to last? I've been out of work for 3 weeks and can't go back until I stop feeling dizzy and can stand up/walk for a full 8 hours.
