Addiction to cocodamol ...?

I have been addicted to cocodamol for about 3 - 4 years now, the 8/500 ones and about 4-12 a day. The trouble is I am now 34 weeks pregnant and last week my mother really made it hit home at the dangers of taking them, so around 3 days ago i just totally stopped taking them as I am absolutely terrified about the baby being born with withdrawel symptoms, I even went to my GP and explained to her about it. She said if i stop now the baby will not be born with any withdrawel symptoms. I was/am also worried about my baby being taken off me. I just cant get rid of the guilty feeling and just wondering if anyone else experienced anything similair? I am currently feeling really sore, tired, very teary and all together just not very nice.
