yup....physical dependence is another kettle of fish from addiction.....the falling asleep at the wheel not a good thing, no matter the cause....have you ever been checked for narcolepsy? perhaps 10 of oxycontin 3x daily would be better? same amount of drug, just wont peak and valley the same....on the other hand, is it actually doing anything for you? it is a small dose, especially for a big guy......i am wondering about your sleep quality? Do you have a pool that you can use? have you been checked for gluten sensitivity? You and i have both been around this board long enough, i cant remember,lol. you know that what you drink can effect you, please also know that what you eat can as well....good luck
