No one will really write my diagnosis as having Arachnoiditis but they assumed it can be. Now I am on Lyrica and Cymbalta to control all the pain I am having all the time. I don't know if i will say thanks for the medicine that i have less pain because i am drawsy all the time. The question is is it fine if i continue drinking coffee and tea like I used too. I have read Cymbalta will be more slowly eliminated by the liver with coffee. What should I do to fight the drowsiness and function as a Mom. Any help will be well appreciated.
