This is DawnKevies mom, my father in law takes the max dosage of lyrica for trigeminal neuralgia. He has gained weight about 25lbs. He also is very tired all the time. However, this is worth the sacrafice to him as it is the only drug that helps his pain. As of late, he has also had a problem with water retention which the dr. thinks may be linked to his lyrica. Good luck!
