Booted 'Bachelor' Contestant -- They Knew My Weakness ... But Still Handed Me Drinks

Freshly booted "Bachelor" contestant Jordan Branch -- who got bombed on Monday's episode -- is claiming she told producers she was worried about boozing on the show, but they did nothing to address it.

Branch tells us ... it was hard to watch last night because she blacked-out the night of that taping. She claims her cringe-worthy behavior was fueled by non-stop drinks provided by producers.

Branch says during the casting process ... she raised concerns about the amount of alcohol in the "Bachelor" house. Once taping began ... she believes producers manipulated contestants by constantly refreshing their glasses.

But sources close to the show tell us … while they do provide booze, plenty of past and present cast members have done the show without touching a single drop. We're also told all contestants are free to make their own decisions about drinking, and sometimes those decisions are "not good ones."

Fact is, anyone who watches the show knows most women don't get black-out drunk.

Branch thinks the show should have a booze babysitter for future contestants ... to cut off buzzed women, much like a bartender would. For the record ... she admits overindulging frequently, but insists she's not an alcoholic.

Fun Fact: She offered "Bachelor" Chris Soules shots when they first met.
