Lantus and rapid heart

I too have experienced muscle weakness (especially in the legs), cramps, bloating, weight gain, skipped beats, rapid heart beat, swelling, diarrhea, insomnia and high morning blood sugars. Each time my dosage is increased, the more negative side effects occur. I'm not sure about this drug. What would happen if I reduced or stopped the dosage?

after taking lantus for a little over a month my heart takes off and beats very hard and i also have touble sleeping even with the help of a sleeping pill

My wife began using Lantus approximately 2 weeks ago
(11/21/05). Very early on Thanksgiving Morning, she
awoke with her heart skipping beats. She had not experienced this before the Lantus injections. We wound up
at the ER at the local hospital on Thanksgiving morning in
Cranford, New Jersey. The Chief of the ER was on duty and
after hours of blood tests and being hooked up to an EKG,
he told my wife to immediately discontinue the Lantus
injections and return to Novilin 70/30. However today is
12/05/05 and her pulse is still erratic at times.
Has anyone experienced problems with their heart rate
while using this medication? Please let me know.
Thank you!!!
