"i did/am experiecing the tingling everyday in my fingers, i am not hungry.  i did have the brain fog to where i wouldn&#039;t drive.  i wouldn&#039;t make any decisions about anything without talking it over with someone i trusted first. i am now up to 75 in the morning and at bedtime and i still have the tingling but the fog has been lifted the headaches are so much less but i have only lost 3 pounds.  can&#039;t seem to stop smoking even with this.  still hoping this will help with the smoking.  wish me luck"
