Hi,
I've been having slight dizzy spells almost every time I stand up. My peripheral vision sort of dims or darkens and then comes right back. The spell usually lasts only for about 3 seconds. It's started only recently, about a week ago, maybe less. Since last night though, I've had a bit of a heaviness in the back of my head. I 'm not quite sure how to describe this. It's not even a heaviness, just a sort or queer sensation. Like an impending dizzy spell that never comes. I felt a little lethargic yesterday as well as today.

Now a little background. I'm a 27 year old male who is about 6'2" and weighed around a 100 kilo's the last time I checked, which was about a month ago. I have always been overweight. I have however recently started to lose weight. I've lost a substantial amount in the last month, so much so that I wouldn't describe the 100 kilo weight above as accurate any more. I am staying away from home for a short course, and have significantly cut down my food intake. I don't keep food in my room, so I end up eating only once a day. I walk everywhere I go, and when I'm walking, I feel totally fine. I don't feel any of the aforementioned symptoms. My walks are generally at around 6ish in the evening for at least an hour, usually two. Leisurely, not very strenuous. About 4 times a week I walk to or from class about 15 to 20 mins in equatorial noonday heat. I work out a bit every 2 days or so with light weights. I am also a gout patient, and rely on my meds to maintain some semblance of a balanced diet. However as the meds aren't available here, I have been almost totally vegetarian for the past month, barring beef burgers which I have had twice. Due to the severe lack of protein, I have started using a whey protein supplement, which apparently contains about 7 gms of protein per tablespoon. I use about 2 to 3 tablespoons per day. I also normally have a boiled egg or two with dinner which is my only meal in the day.
