Oh trust me I feel ya. From birth to 3 months my DD had colic, she cried all day and night long. It was awful. I wished for the day that I would sleep again, and it eventually came...lol! It's rough in the beginning for sure, you feel like you might not make it, and it's such a huge life adjustment even when you think you have prepared yourself as much as you can. Hang in there, it DOES get easier on it's own, I just don't want you to waste your money on something that may not work, and even may upset your little guy's tummy.
6 weeks is still very young, at about 3 months you will somewhat have a schedule going and by 6 months after the introduction to solids you may even feel like you have some control back in your life. All I will say is treasure every moment cause it goes by too fast (although I do NOT miss the colicky stage...lol) one day you'll be like me and wonder where the past 2 years have gone. :(
