Egg Donation: Fertility Injections, Side Effects?

I'm about to become an egg donor and I'll be starting my injections very soon. I was wondering, for those who have donated, did you experience any severe side effects? I work in retail and attend school every day, so I have been worrying about how the side effects with affect that. It would be unfortunate if I had extreme mood swings and lashed out! I have heard of people going crazy on the fertility meds and ruining their own relationships from having meltdowns!
