Gabapentin is weird. Up the thread someone says "Thoroughly disproved as gaba-b agonist" but provided no link, that's news to me. Read the study, seems they're right :
In addition, in both CA1 and CA3 pyramidal neurones from rodent hippocampal slices we were unable to demonstrate any agonist-like effects of gabapentin at either pre- or post-synaptic GABA(B) receptors. In contrast, gabapentin activated a GABA(A) receptor mediated chloride conductance. Our data suggest that gabapentin is not a GABA(B)-receptor agonist let alone a GABA(B) receptor subunit selective agonist.
Very, very weird. I haven't messed with faso SPECIFICALLY for nuerontin, I was using it sporadically with the main problems - alcohol and phenibut. So I can't say much about the nuerontin, which I have used very successfully to taper phenibut, which is remarkable considering it is NOT a gaba-b agonist... that's real weird to me. I can say now that I'm off any pheni or anything that faso definitely seems to cause some anxiety, as I'd expect an antagonist at gaba-b to do, I was taking it more like junkies take small doses of naltrexone with a full agonist, to prevent/reverse tolerance while on the drug that did what I wanted - so I didn't notice much of the anxiety re gaba activation

I have noticed since that episode has ended I have left it alone, although my gaba system is still rightly jacked and I am considering a week run of it and just dealing with the anxiety, as I suspect afterwards I may feel a bit better...
