Hi H.! I want to say first that I really feel for you. Our little girl had horrible colic and reflux on top of it too. I did a ton of research at the time and felt completely alone in the situation. Many people think reflux is colic, it's not (as I'm sure you have already noticed).
The first thing that was a God-send for us was the book "Healthy Sleep Habits, Happy Child" (http://www.amazon.com/Healthy-Sleep-Habits-Happy-Child/dp... ). It has lots of information about extremely fussy babies and improved our daughter's sleeping. It lets you know how to schedule their sleep/naps and sticking to a STRICT sleep schedule made a big difference. You can skip right to the section where he breaks the info down by age. However, once you're getting more sleep, there's great information about research done about colic in the book.
Next is that colicky babies need to be swaddled tight, held more (if not all the time which was the case for us), they need to suck (so if she doesn't have a pacifier, get one she loves) and they need help falling asleep. I used to wear our daughter in the sling I made (I wish I had known about the better carriers out there at the time) and when it was time for her to sleep, I would swaddle her up tight, make loud "shushing" noises and would pat her butt/back pretty firmly - all while holding her as tightly as possible. It was hell on my back, but she would take all her naps on me while I worked.
Also, I learned about the "double swaddle" that we ended up using until she was almost a year old. It's hard to explain, but I would be more than happy to draw you up some diagrams and email them to you if you need me to.
As for a pacifier, we got hooked on the WubbaNub (http://wubbanub.com )! We probably ended up having about 7 of the red dogs (we named "Charlie) by the time our little girl was finally off of pacifiers earlier this year.
Depending on the baby, sometimes lots of movement and/or loud music helps. Our daughter HATED all the traditional things that are tried-and-true methods for other colicky babies. Car rides were non-stop, scream-fests (quite possibly, hell on earth) and she didn't like the swing until she was a couple months old. Eventually she moved off of me for naps and into the swing (still double-swaddled). One thing that did help calm her down many times was loud music. She loved the Classical music on HBO's "Classical Baby" series (it still runs on HBO Family) and many other songs turned up pretty loud. I don't know if this will work for you, however; if your baby is experiencing hearing loss or problems.
It WILL get better and I still remember the day the colic seemed to drift away. I'm sure you have noticed this too, but when our little girl would have her episodes, she was not her regular self. She was completely checked-out and her blue eyes almost looked black. Please know that some babies are over it at 3 months, most at 4 months and some have it until 6 months. However, if you get her napping schedule under control, she'll most likely be in the 3-4 month range. We didn't know how we would get through it, but we did. :-) Now we have the major melt-downs/tantrums of a 3 year old. My husband calls some days "Colic Version 2.0". LOL! I guess there's always something to learn.
I want you to know you're not alone. I really wish there were some kind of colic support group (maybe there is nowadays - check with your pediatrician). One thing I did at the time was to keep notes of each week and write a weekly journal for our family and friends to read. You start noticing what things make for worse and better days. Now I have a great record of what the first year of being Ava's mom was like. Plus, because I didn't want to write about all the worst moments, I can go back and remember that we had lots of wonderful moments too during that tough time.
Finally, I want to tell you that in our PEPS group (a parents group here in Seattle) we went from having the highest maintenance baby that was the hardest to get to sleep (I even slept with her in the La-Z-Boy for 3-4 months) to having the easiest baby to put down for naps or bed by the time she was 8-9 months old. So, I'm a true believer in the book I mentioned above! Good luck - you're in my thoughts!!! :-D
