Everybody is different, and people develop tolerance. But this drug, which is basically a muscle relaxer, makes most people sleepy and unable to drive on the regular dose of 4 per day. Whether you had them all at once, you would Od. Like any other depressant, such as alcohol, it can kill you if you have enough at one time.
a little over recommended dosage will make someone uncomfortable perhaps abdomen pain... a little more than that will knock someone out and make it tough to breathe... and a bit more will probably kill someone or put them in a coma if not you will have severe liver damage and a lot more complications...the daily dosage is 250 to 350 mg three times a day... im guessing over 2000mg would do a lot of damage if not kill someone... thats 8 250mgs and 6 350mg tablets
