some had seizures while taking chantix. if you have any of these, stop chantix and call your doctor right away. tell your doctor about any history of mental health problems, which could get worse or of seizures. don't take chantix if you've had a serious allergic or skin reaction to it. if you have these, stop chantix and call your doctct right away as some can be life-threatening. tell your doctor if you have heart or blood vessel problems, or develop new or worse symptoms. get medical help right away if you have symptoms of a heart attack or stroke. decrease alcohol use while e king chantix. use caution whenenriving or operating machinery. most common side effect is nausea. man, i love being a non-smoker. ask your doctor if chantix is right for you. i'm jerry bell the second. and i'm jerry bell the third. i'm like a big bear and he's my little cub. this little guy is non-stop. he's always hanging out with his friends. you've got to be prepared to sit at the edge of your seat and be ready to get up. there's no "deep couch sitting." definitely not good for my back. this is the part i really don't like right here.

them as warm a welcome as possible. >> we expect this to continue throughout the winter. i'm afraid it's going to happen. i fear we are going to lose some lives. somebody's going to freeze to death somewhere. >> reporter: inside the family has rested after their long trip and is trying to come to terms with their n n reality and what lies ahead. >> how are you feeling right now? >> unhappy. >> unhappy? because you're not at home? >> reporter: as hard as it is to leave home and loved ones behind, seeing your country torn apart, the pain is compounded for so many like this family and this man when forced to accept their new status at refugees. >> i don't know, i'm regretting my decision to emigrate. yeah, i'm seriously regretting my decision. >> reporter: for so many of the hundreds of thousands trying to make their way to europe, it's
