I have been taking Lyrica for 2 monthes, and now I.am prescribed Ultram ER 200 mg one time per day. I have had 3 nights of complete insomnia. Of the last night, I was up vomiting and felt terrible. I am not sure if any one else has had this same interaction, but I would be curious to know. The Lyrica dosage is only for 150 mg per day, split in balanced intervals. I really cannot deal with the pain, but I cannot be experiencing insomnia and vomiting.Please help!
