I received some hydro and they were HUGE blue pills with M361on one side. I don't doubt they are the 10/650 I ordered, (libertymeds.com) but they are not effective at all!!! I don't get it. I had Watson brand before, and they worked really well. I thought all hydrocodone was the same generic or not? Has anyone else experienced this? Thank in advance for all your responses!!! Trish
