Energy drink- guilty?

Coffee makes me want to vomit lately. But dutch bros has an energy drink (rebel) that has only 160 caffiene for a small (a little over half the daily intake allowed for pregnant people) and b vitamins. I've been desperately craving them and I caved and got one... and it seemed to help with my nausea. I dont eat anything else non recommended and I looked it up and it only recommended to look out for not going over caffiene content on a pregnancy site that judged caffiene filled drinks.

But I cant help feeling sort of guilty. I know they're not the best but I need SOME caffiene and coffee or other teas and drinks make me vomit. This is the only thing that I've not only kept down but it seemed like it also helped?
