That's just a huge lie. All of the essential amino acids can be provided by a vegan diet - and it's not hard to do, just eat a variety of food, and enough calories.
So considering this, even if people have experienced different mood swings since becomming vegan, if could be for a whole hoard of reasons including their age (ie: pubery/meopause), what they eat (ie: high refined sugar diets causing your moods to go up and down), a medical condition/problem, stress, emotional problems, or it could be psychosymatic.
Everyones mood changes, and if you start to think about it you can think your having more mood swings than normal when infact you're just noticing your changes in mood more acutely.
Also, you said you've only been vegan two weeks, I'm not a doctor but I'm fairly sure that's not long enough for any sort of deficiecy to develop - I know you can store enough B12 in your body to last you years. (Btw, B12 is a vitimin you should be taking - or you should be eating fortified B12 food - as a vegan as it's the only thing a vegan diet DOESN'T provide
). I have seen a lot of new vegetarians or vegans claiming to feel weak, dizzy, tired, lathargic, experience mood swings, etc etc etc, and it turns out they only became vegetarian or vegan a few days or a couple of weeks ago. I think people can worry unnessersairly and convince themselves they are feeling ill/different to normal, because it's how they expect/are worried they may feel.
This doesn't nessersairly apply to you of course, but it's something to bare in mind. A varied diet with enough calories should will provide enough amino acids. If you are worried about vegan nutrition you could take a look at: http://www.nhs.uk/Livewell/Vegetaria...egandiets.aspx
