Yes, I do have that. My arms and legs are asleep. My legs are so numb I do not really understand how I am able to walk, but I do. I have no small nerve fibers in my feet and lower legs. I cannot tell whether my shoes fit, or how tight to make my leg braces, I have to go by whether they leave red marks. It is frustrating, but you do get used to it, at least I have.
My fingertips are numb and typing this leaves strange sensations in my hands. If I thought about all of the things that don't feel right I would go crazy, but I usually don't think about it .
Your problems developed suddenly whereas mine has been a lifelong progressive neuropathy and I am sure that makes a big difference. You haven't had time to adjust to this, but as you said these things are not exactly painful. It sounds facile to encourage you to pursue distractions but it really should help.
You do get used to these things. Going up to 1800 mg Gabapentin may help some with the electrical zaps, but the numbness, or feeling like your limbs are asleep, is probably something you will have to accept unless a cause is found.
