John, I know people are probably giving you a ton of advice. But we have been there (our son is now 2). Have you tried a swing? It was a LIFESAVER for us. The only way he would calm down. Even when he was small, we just rolled up receiving blankets and propped them beside him to keep him snug. We were pretty clueless about babies and felt totally helpless during those crying jags! Just remember, it may seem really rough but it WILL go by so quickly. (Also you may just black it out from sheer exhaustion)
Also, the other person who said it is just gas not smiles is WRONG! Also, a good book to get is The Happiest Baby on the Block by Dr. Harvey Karp. Has some good techniques for dealing w/ colic. It WILL get better and more enjoyable!
