I have been on Lyrica since 2008 for Fibromyalgia and Chronic Fatigue Syndrome. Due to financial situations, I have had to do without, for brief periods of time. The withdrawals I have are terrible. Profuse sweating, chills, nausea, joint swelling and tenderness, IBS, vomiting, crying, severe headaches, inability to eat, etc. Some of these are the effects of my Fibromyalgia. Lyrica has been a miracle drug and has kept me from becoming bedridden. However, the fact that it is highly addictive and expensive is a downside. Also, these withdrawals makes the thought of not having it put fear in me. I start experiencing withdrawals within 12 hrs of a missed dose and the withdrawals had never gone away, until I began taking Lyrica again.
