It seems they give Gaba to everyone these days. They don't know what to do without Opioids. Gaba is not good for all things. It is good with small nerve pain like neuropathy. A little goes a long way. They increase the dose thinking that more is better. More is not better. It more likely is not working for the persons type of pain if they need high doses.
It is also good in lower dose with combination lower dosecocktails like Motrin/Gaba/Sineguine.
( all lower dose).It also seems that your brain establishes a memory for the drug and you can go on and off and it does not take weeks to help.
I hope this helps.
