You're ony on for a short therapy time. 15 days is the norm and in that time you won't have time to swell up or overeat. I've been put on short course therapy of 15 days with much higher doses with no ill effects. But I can tell you that each time was well worth it and if I ever needed it again I wouldn't hesitate to go on again. I think the only side effect is that you have trouble sleping but then your pain would keep you awake wouldn't it?
