how do I know when to try gas drops?

How do I know when I should try gas drops for my son? He is 6 weeks old and the last two or three nights have been a nightmare. He does not want to sleep, and when he does he's up again in 3 hours or less and he is just super squirmy even swaddled. He sometimes has trouble burping and sometimes he won't burp at all, but his bowel movements seem to be fine. Should I try gas drops? I read that some moms saw a huge difference after trying it out, but I don't want to give him something if he might not need it. Thanks ladies!
