Has anyone used the MAM bottles? Need help! Severe acid reflux baby?

My son uses the MAM pacifiers, and was wondering if anyone has tried these bottles and what u may have thought of them? See my son uses the Dr. Brown bottles which r great, but he has severe acid reflux and it recently flared up very badly and now when he sees the sight of his bottle he arches his back and twists his head and fusses. He is on the medicine Prevacid and Zantac. He will only eat maybe 2 oz at a time. the last few days all he will drink is maybe 6-10 oz a day. I mean yes he eats lots of jarred food, but he needs his formula. I am just at my last rope and i dont know what to do anymore. AND when he does drink from the bottle he doesn't suck right, its weird he like just flicks it with his tongue, there is no suction. BUT with the pacifiers he has a hard suction. He does use the 6 month plus pacifiers. I seen online that they have a MAM bottle and the looked similar to the pacifiers. I was just wondering if anyone ever used the bottles and what they thought? He will be 6 months soon. Also he is on Similac Alimentum formula.
