Gabapentin
"At first I was very light headed on a dose of 1800mgs a day. After a several days I levelled out, now all I know is I cannot move a muscle in the morning, until l have had my dosage with other painkillers too (tramadol). But it was the gabapentin that helped more, my consultant thinks we have to find the correct cocktail of drugs that will work individually for each of us with differing pain."
