Right, I have a reoccuring problem that is really annoying. I was training hard in the mornings and you can see by my log everything was going smoothy. I've been lazy/ haven't trained as much as I should have in 2007 (due to this I think) and I was trying to fix this firstly on my own then reintroducing the thai when my base level fitness was high again. Now, after about 14 weeks of this (i think the most I had had off in one go was 2 days), I thought due to a bit of a flare up on my knee I'd back off and have a week off to recover and then I'd go back into it. 1 week got rounded to 10 days...that was almost 2 weeks ago. Last week I went back into it, mon, tues and wed (HIIT work.....*cough*), but then got ill. I became woozy on the wed night, a temp on the thursday and friday and had the sweats and shakes sat and sun. I'm back at work today after taking about 15g of vit c over friday, saturday and sunday, but I'm trying to work out what I might be missing that might make me ill/reduce my immunity. From thursday-now I have a cold sore and 2 ulcers have developed on the inside of my mouth, plus leading up to wednesday I wasn't eating as much as I should have been due to lack of funds (breakfast was a couple of eggs, some spinach, some olive oil, some spinach, some feta cheese, some cold meat in a pitta, 11 am would be a bagel with peanut butter and honey, lunch veg [peas, broccoli, sweet corn] with meat [ie chicken, tuna steak etc] and after that I would have a mixture shake from the morning that would usually have spinach, milk, yoghurt and some kind of fruits like blueberries in it). It seems like whenever I get back into training, something along the way gets me and I have to basically build back up all over again and again and again (which is why I had 2007 mostly off because I got sick of it. I almost started to fear pushing myself because it might make me ill. That really has a serious blow to your confidence you know).
