"i&#039;ve been taking this medication 10mg 4 x a day and it has really helped. i was initially taking hydrocodone for about a year until having surgery (fusion and laminectomy - l5 s1) and i have to agree with some of you, when i first started taking it, it worked great and provided relief for about 5 to 6 hours. now after 6 months, it doesn&#039;t seem to be working as it used to but i will be talking with my doctor next month regarding this issue. it seems to only work 3 to 4 hours and does not provide relief like it used to when i first started taking it. i broke one tablet in half since they&#039;re scored and took 15mg and this worked but it tells me i&#039;m becoming or am dependent on it. i tried to go without it for 3 days and i hurt worse and vomited."
