Hi, welcome to NeuroTalk.
I started on Neurontin and came to increase it after 10 years, until I was at 4200mgs/day as well as Tramadol (Ultram) 400mg/day.
Eventually, the Neurontin just wasn't working well enough for me.
I switched to Lyrica & Tramadol and believe the Lyrica to be a life saver.
If not for this med, I would not be able to get out of bed in the am.
I work with power tools and drive in my line of work, as well. I found that the 'fuzzy head' subsided after the med had a chance to be in my system 24/7 for a few weeks. After the first month, I had no problems driving or working with power tools. I haven't had a car accident and still have all my fingers and toes after 7 years on Lyrica. Drugs affect different people differently - that's why there are so many different kinds. You eventually will settle down to one that works best for you, just be patient.
