Suspecting acid reflux 🤮🤢🥱😖

My baby is 7,5 weeks old and started to be extremely fussy, especially whe I try putting him to bed. He started to do bigger vomits, and last night he was exclusively sleeping only on me or my husband in upright position. If we were laying him down, he started making noises, grunting, making swallowing and crying noise. He also has trouble or doesn't like to drink from my right boob (my guess - stomach position is bad). So by now I am pretty certain my bubs has an acid reflux, but I am just so exhausted and can't sleep with him all night like this. He is tried and cranky too... What can I do to help? Is there a way to improve this?

P.S. I am not going to give him drugs, as I read that they are either straight out dangerous or ineffective.
