Hey, for the last year I've been having this problem which is actually really affecting my life, heres a list of whats happenning from about the afternoon onwards:
1. I always feel really light headed.
2. I just can't concentrate.
3. I constantly get mild headaches.
4. Sometimes I just blank out randomly for a few seconds, and after sports it happens again and in the last football game I just collapsed suddenly on the pitch after around 80mins.
I mean I haven't taken any knocks on my head or anything, so it can't be a concussion. But for the last month I've tried to see what is wrong: I got more sleep, I drank more water, I ate more food and took vitamin supplements (I'm a vegetarian) to see if it is caused by a lack of something and well nothing seems to work. I even tried not watching TV or look into any monitor really to see if it is caused by looking at screens for too long.
I was planning to just leave it, but I need to sort it out because I've changed my driving lesson times to around 4.30pm (from the usual mornings) and its having a devastating effect on my driving. Also its approaching my exams soon and they are all in the morning and I'm afraid it may jeprodise my exam performance.
Thaks for reading, any response would be helpful.
