I'm over 31 week now and only just starting to control them. I was on meds pre pregnancy but weren't safe to continue. Lots and lots of water is all that helps me. Resting when you can (hard with other kids, I've put DS into care more to help allow more rest time). Speak with your GP, they might be able to give you some help how to manage it better.

Drug wise I take Panadol Osteo rather then usual Panadol. Ill also take Panadeine Forte when I hit breaking point, but the constipation side seems to sway me against it lol
