I don't know about the two bowls. I have a pretty healthy tollerance. I can tell you that I have much less partial seizures than I used too while I smoke. I am talking every hour taking two hits and continuing on with the day. It is soooo much better than phenobarbital or Topomax...sigh. Topomax is aweful!! Side effects are similar to Dialantin. I don't take anythin anymore, except keep valium for emergency.
