Hi brandy I too had (still a bit over powering at 6months!) over supply & fast letdown. My lo slept on me or DH A LOT in the early days! it does get better but there are also some things you can try to help. Kellymom website in particular is worth a look. Things like positioning little one so he has to suck upwards slightly (if that makes sense!)so milk doesn't just shoot down his throat. And frequent winding!
I have had a number of occasions when feeding while out where I had to e careful not to spray nearby people! Most notably in costa coffee! Because fast let down & over supplyoften causes fizziness at breast, coming off and on etc.
My dd1 had reflux & h/v was keen to suggest dd2 did too, but having lived through it once she definitely doesn't! It's just my over active boobs! Behaviours can be similar though so consider all options.
It definitely gets better though! Congratulations
