You'll feel something from even 1 if you never use kava. I usually drink several cups of Kava tea which has about 100 mgs per cup. No matter how much you take, you aren't going to get that messed up. Just pop a couple, in a few minutes if you want more, have a couple more. The dosages of Kava are realy not very distinct. You can judge how much you need. I don't know for sure, but you probably could just eat the whole bottle.
