Whoa, so many replies. Let's start at the beginning:
Aurelie (et al) - it's good to hear that you're getting good results, but I wouldn't even begin to consider Atkins as a viable alternative

First of all it's just wacky and counter-intuitive, and on top of that I don't like the taste of fat, or beef. Also, greasy foods (even our typical codfish covered in olive oil) gives me heartburn. Coffee is the same. The prospect of getting bad breath / BO completely turns me off to any diet involving ketosis.
Chip - food is indeed an addiction. I had a lot of problems cutting down at the beginning, I was often hungry and looking at my watch, waiting for the next "fruit time". But after the first week or so, it was the opposite. I'm having trouble finding room for the bi-hourly apple/orange/pear, which probably means I should cut down on the meal size again.
My biggest problem is the habit of filling up the dish. I need to get some smaller dishes and bowls so it won't visually seem like I'm eating too little.
Pituca - I actually had to look up what people mean by mediterranean diet. Whoever came up with that term was certainly on crack

No one eats like that around here. That sounds like something out of the middle ages when meat was a luxury. Today, its fish that is a luxury, being twice as expensive as meat. It definitely looks like it might be healthier, but sadly I can't drastically change what I eat because I'm still living with mom and so I'm subject to her dietary habits.
Devlin (and MJ) - Thank you, that's exactly what I'm doing. Why not follow your own advice, devlin, werent you the one who weighed 300 pounds

Del - I did quit SL. Mostly. I just log in once in a while to take care of some loose ends and chat with my old friends. As for getting outside, I would love to, but living in the middle of the capital, all that getting outside would bring me would be lung cancer.
Ama - We do get free doctors around here, but we get what we pay for

They are IDIOTS! Completely ignorant bastards. I can get more info out of google. So many times I have been misdiagnosed, or even worse, NOT diagnosed. I complaint about something and she tells me not to worry, its normal, or its nothing serious, or even refuses to look at it.
I recently found out that I have psoriasis, by talking to a friend of mine (who is a med student though) about a skin problem I've had for 3 years, and then googling about it. My stupid doctor wouldn't even take a look at it, the first time she said it was nothing and that it would go away, the second time she thought it was just dry skin and prescribed me some moisturizing cream, the third time she thought it might have been a fungus and prescribed me some anti-mycotic. I'm never going to set foot on a "free" doctor again unless my life depends on it.
The psoriaris cream is working wonderfully though, my hands are MUCH better now.
I've also had a life-long history of suffering from bouts of dizziness, starting to see black and even fainting once, and lately I had sudden bouts of hunger accompanied by shaky hands and even cold sweats. Where was my doctor during all of this?
1st diagnosis: "Dont worry, its nothing, its normal, and it will go away"
2nd diagnosis: "Well you're really tall, and when you get up all of a sudden your blood has difficulty getting to your head on time"
3rd diagnosis: "Dont worry, you probably just have low blood pressure"
4th diagnosis: "So you're telling me that after going without food for a while you start feeling faint and very hungry? Well thats what you get when you dont eat for a long time. You get hungry."
Turns out I have hypoglicemia

Getting any useful advice out of a portuguese doctor is like getting blood from a stone. You see, these people are paid according to how many patients they can get rid of in the same day. They are actually instructed not to waste more than X minutes on each patient.
I wasn't really looking for diet tips, I think I got the food thing under control, it's mostly the exercise bit I need help with. I have been steadily increasing it, but I dont know if I'm doing it right.
Like, for instance, when do I know it's working?
Should I do 5 miles (which doesnt get me very tired), then stop, then do another 5 miles?
Or is it better to do 10 miles and get all sweaty and panting, with my muscles all hot and burning?
When I did some body building, 5/6 years ago, I was often sore for days in a row. These days, I'm never sore for more than 5 or 10 minutes.
Does that mean I dont exercise enough?
I need a personal trainer more than a doctor, but alas I cant afford anything like it
