Hi Sal
My baby boy (he is 15months now, and btw the EASIEST baby in the world now!!) was the "colic baby of the year"! He had colic so badly,- or so I thought -!!
I tried, telement drops, some homeopathic drops that was a total waste of money, did the baby massage-thing, took him to the chiro, gave him bennets colic mixture, both colief and colix, buscopan, losec etc etc, the list just goes on and on! Obviously I only tried one thing at a time..!

NOTHING HELPED!! the bennets helped a bit, but I think the alcohol content in it just zoned him out and made him fall asleep. The chiro helped a bit.
The day when I put him on Soya milk, my baby changed from being impossible-impossible, to the happiest/easiest baby in the world!!! So, he obviously had a huge lactose problem. (you also find lacotse in breastmilk - as even my breastmilk made him sick!)I later confirmed this with a blood test.
I know some babies react really well on above meds, so unfortunately you have to figure out whats working for your LO. It might be that he is really just colicky and windy, but then usually medicines helps.
Good luck!!! I know SO well what you going through!!!!
