I mean it helps if you're an optimist basically, as opposed to the opposite. I mean, if you're too much prone to sort of giving in too easily and doom and gloom and nothing easily and nothing else is on your horizon, then you're going to have more of a problem with these pills because there will inevitably be days when one of the pills is upsetting you in some way or another. There will be problems with occasional side effects from them, or indeed some of the HIV symptoms may themselves blow up, and it takes you a little while to get treatment for the individual symptoms, and for these… for the treatment to take effect upon those things. So there's no point being worried, you just have to accept that…
