Anti biotics

So basically after complaining about them i'm having to take a 6 week course of them again, erythromycin if you were interested. Their common side effect is nausea. This combined with my mum's 'pick me up idea' of getting me a David Lloyd membership I've estimated I'll either be banned from the gym for vomiting within a month, or will have accidentally halved my bmi in that time. Dang it.
