Probiotics and gas drops?

Anyone giving both? We started giving probiotics last week to try and help with spit up. It seems to have helped a bit with the spitting up but I also stopped using gas drops and now my LO has been really fussy overnight. Not sure if it could be from the probiotics or from not getting his gas drops before bed.

Is it okay to do both? Should I do probiotics in the morning and gas drops before bed maybe?
