I too have been taking Lyrica for the past 3 years. I recently had to go back to the Dr for refills, in the meantime I ran out. It has been 3 days and I feel terrible, can't sleep, going from freezing cold to sweating, and (not to be gross) but upset stomach with diarrhea. I wasn't sure if it was the Lyrica and withdraw or not but after reading some of your posts I think thats what I am experiencing. Buh!
