Simvastatin
high cholesterol
"I am on 20mg.  I take it right before I go to bed.  After 15 minutes my heart starts racing.  However, I have no problems falling asleep.  If I had to take this in the morning I wouldn't be able to stand the racing heart.  Other than that, I feel good so far.  My cholesterol was 204 & triglycerides are at 130.  I am 43 and have started walking 3 miles at a good pace 5-6 days a week.  Drinking lots of water and no caffeine.  I have just had my next blood work since being on this medicine, so we'll see if it's doing it's job."
