Do whitening toothpastes work?

What should I do to reconnect with distant boyfriend?

I wanted to ask you a question that I can’t even answer myself. Well, I have a boyfriend and we’ve been together for seven months now. We both love each other so much and I always make sure he knows that. I do everything for him: cook, clean, wash clothes, practically everything to make him happy. He used to be really loving with me. I mean, he still is, but I feel as if he’s changed in some way. Before, we used to be able to tackle our problems and if we argued, we would sit down and fix the problem. Now, he just ignores it and leaves, and smokes his weed. What’s your advice?


Are my tremors from marijuana use or anxiety?

I have smoked marijuana on and off for about a year, not ever more than about once every other week. The last two times I smoked, I experienced uncontrollable tremors in my leg. It wasn't painful like a muscle spasm, but it was uncomfortable and unsettling. Was this merely nervousness (this was the first time I had people "over" at my own suite to smoke and I was a little worried that my roommates would be angry)? Or, could this be a side effect of the drug?


What to do about bleeding nose and gums?

I just came here this fall. Since then, my nose has been bleeding occasionally without any injury. My friend told me it was because of the dry air of U.S. Is he right? How can I prevent this situation? I also have a problem when I brush my teeth. My gums are always bleeding and not just a little!! What should I do? Thanks.
