First time on antibiotics- any suggestions?

So I have a gum abscess (luckily not painful but fairly large) and I have to take 250mg of amoxicillin for it daily. I've never been on antibiotics before. I'm going to be taking probiotics with the antibiotics but I'm still really scared of side effects, specifically nausea and vomiting. Have any of you guys had experiences with amoxicillin? Were they positive or negative? Is there any way I can minimize side effects? Thanks :)
