I have post herpetic neuralgia. I went from taking Lyrica 150MG 2x/day to taking Gabapentin 600MG 3x/day. This is the end of Day 4 and I am still getting shocks in my upper right teeth but have not had to take any Tramadol for 2 days.
When taking the Lyrica as mentioned above, I was pain free for 10 months and then began to get "zingers" again. My neurologist allows the switch due to the cost difference of the medications.
I'm taking 3600 mg of gabapentin and it's been 3 months, I've increased about every 2 weeks because the effects would ware off and the pain would become more pronounced. I still experience pins and needles, burning, hypersensitivity, and temp changes in my legs, feet and arms just probably at a level 5-7 on a scale to 10 now. I hope it goes away, I have PHN but with Herpes Simplex.

I never had much success with Gabapentin. Never worked nearly as well as Lyrica

I am taking gapentin for neuropathy in my feet and I don't have diabetes so they don't know what's causing it. I find I take it 15 minutes before it's due as I'm taking 600 mg 4 times a day. Then I developed Trigeminal neuralgia which the gabapentin didn't help. I felt like I was dying from the pain. My neurologist started me on Carbamazepine twice a day plus tramadol when they occur but with an ice pack and this it still takes 45 minutes to subside. I also use oxygen from a platinum 10 invicare that my son picked up on EBay which helps but they still come with no warning. Yesterday I was switched over to Verapamil so only 2 days on this but knock on wood as no headaches yet. I've also had MS for 42 years and that's stable though so I wish they would stop blaming it on my MS. Upon further examination they felt my Trigeminal neuralgia is a combination of cluster headaches as well. Hope this helps and good luck as I feel the pain you are experiencing.
