Is It Safe To Take Neurontin And Lyrica To Treat Fibromyalgia And GERD?

Hi. I'm a 63-year-old female, 210 pounds, whose health conditions include neuromas in my feet, neuropathy, fibromyalgia, and a non-specified auto-immune disorder. With a 33-year history of severe GERD, I haven't been able to use NSAID's during most of that time. My doctor prescribed Neurontin 600 mg. 3 times/day, plus Lyrica 75 mg. once/day at bedtime or with dinner. Is it OK to take the third daily dose of Neurontin with the one Lyrica dose each day? Thanks.
