I am not sure if you are breast or bottle feeding, but if you are on bottles have you tried Dr. Brown's? IMO they are the best bottles on the market (I know, tried them all in a fit of desperation). Also, have you tried 'Infacol'? or 'Colief'? and I can highly recommend 'Gripe water' added to her bottle. Maybe you have tried all these? I'm not sure but just thought I'd share.... HTH
BTW My son suffered from terrible wind/colic 2 weeks after birth until I found Dr Browns. He was able to bring his wind up more effectively by around 14 weeks and by then it seemed to ease off.
I really feel for you, Colic is not fun.
