One. I've really been having trouble sleeping lately. That's too bad. Yeah, I go to bed, but I often can't fall asleep. Do you ever have that problem? Yeah, I sometimes do too, especially if I'm feeling very worried or stressed out. So what do you do for it? Do you take sleeping pills? I don't like the idea of sleeping pills, so I usually get up and watch TV, or read until I feel tired. Then I go back to bed. Why don't you try it? Yeah, I will. Two. I've been feeling very tired lately, like I have no energy. Really? I used to have that problem. Oh, yeah? Do you think I should see the doctor? It may not be anything serious. Have you tried taking vitamins? No, I haven't. Taking vitamins always helps me when I'm tired. Three. I've been getting really bad back aches. Is that right? Yeah. Sometimes the pain is so bad I can hardly move. Do you spend a lot of time in front of a computer? Yes, I do. That's probably causing it. I used to get that problem too. So did you stop using the computer? No, I didn't need to, but I changed the way I sat and that made a difference. Here, let me show you. Four. I'm getting a lot of colds this year. Really? Yeah, about once a month. That's too bad. I've been taking vitamin C, but it doesn't help. Well, maybe you should go to the doctor. Maybe you're right. Can you recommend a good one?
