I tirated the switch from Neurontin to Lyrica at full Lyrica dose of 450mgs/day. It worked, but still felt as if a bit more would do better.
My doc increased it after I had been at 450mgs/day (150 3xday) for about 6 weeks.
I was increased to 600mgs (200 3xday).
The Tramadol is taken in 4 divided doses of 100mgs each.
Together they have brought me down to a very manageable pain level(Mankoski scale) of 2-4, and on good days a 1 (bad days 5-6)!
