Bioshock Infinite..lost my Vigor?...

I got to the point where I picked up and drank the Bucking Bronco Vigor, and it worked fine, but then I seemed to have lost my Murder of Crows Vigor. I can only toggle between the Bronco and the Possesion. When I go into the settings, I see Bronco and Posession are equipped but I can't change what is equipped. I'd like to get my Crows back. It just says they can be upgraded but I can't equip them. 

Are Vigors gone after you find another? Or is there a away to equip them all and rotate? 

Kinda stumped on this one..thanks

Frank

tere should be a button that brings up a wheel on screen. You can choose your vigor there. 

I can click the LB and it toggles between Bronco and Possesion, I only see those two. So I HOLD the button and it brings up other Vigors? As for the wheel on screen..how do I access that? I have not seen it. Lastly..can you lose a Vigor? Or does it wear out? I assume after you drink it you have it forever. Thanksfrankmcma

The wheel on screen shows up when you HOLD the LB...Then you can select your vigors from there. You only have two slots for IMMEDIATE usage or anytime you click on the LB you will circle between those two slots. So, equip whatever vigor you want from the wheel (HOLD LB) to the two slots, whch are interchangable by clicking the LB.

Vigor uses Salts. Consider Salts as the Eve's equivalent from the original Bioshock. While you cannot lose a vigor, you can run out of Salts, which you can replenish along the road.

Good luck!
