PLEASE READ! Mama needs help!!! Extremely gassy baby.

I have a really gassy 6 week old. His stomach gurgles alot and he scrunches, wiggles, grunts and is so uncomfortable. I've tried Mylicon and Gripe water. Both have seemed to work for a while but now I'm noticing that baby boy is not getting much relief. It's waking him out his sleep and hard for him to get comfortable. It seems he's in pain as well. I've tried massaging his belly, the bicycle movements, sitting him up, laying him on his belly (seems to be the best alternative at the moment but not 100%). We go back to the Dr. on the 16th but I can't hold out that long with my baby not feeling well. He eats well (EBF) but I have noticed a slight decline and he falls asleep at the the breast often (not usual for him) he still nurses every 2-3.5 hrs. I assume he's full when I take him off and put him back on and he still doesn't suckle and swallow buy I'm not so sure he's actually "full".

I'm not sure if maybe it's my diet, his digestive system maturing or what the cause but I need some relief for my sweetheart.

Anybody have any advice, solutions, things to try? I'm really desperate right and want to try to fix it at home and exhaust all options before resorting to the doctor.
