nauseous

I'm not going to use protein powders anymore they tear up my stomach too much and they make me feel nauseous all day I'm looking for something instead that will boost my protein intake. should I transition over to protein bars or should I take protein pills instead?

So i screwed up my injection I was so nervous cause it was my first time injecting I accidentally injected an air bubble and now I'm scared. I also feel very nauseous and I feel like I'm very busy like I'm going to faint. Should I run to the emergency room or will I be okay? I’m only 21 years...
