"Been taking this medication for the second time first for an absess then tooth was taking out now for dry socket & I can't wait to finish them , I feel awful - so tired all the time , ( slept all over new year ) feeling drowsy headaches blurred vision , finish them tomorrow thank goodness.  I've been taking 200mg 4 times a day for 5 days just hope it's the end of my nightmare"
