I used to take 400mg Gabapentin and 75mg Lyrica for many years. I know they are similar but that combination worked best for me rather than increasing the Lyrica dose. At the time Lyrica only came in 75 & 150mg strengths. 150mg three times a day had too many side effects. Now that I have withdrawn from Lyrica & Gabapentin I am thinking it may have been easier to taper more gradually by using smaller doses of Gabapentin. I was unaware of withdrawal problems with these drugs. At the time I just stopped taking the Gabapentin. I had problems but nothing like when I began to decrease the Lyrica. I am sure you will experience problems withdrawing from the Gabapentin. In my experience it just wasn't as severe as the Lyrica. I could only just manage to decrease 25mg Lyrica every 2 weeks. The horror of it was indescribable. I probably should have broke the capsule open and divided the dose that way or tried to decrease more gently by using Gapapentin at low strengths.
