Boozing while on Proton-Pump Inhibitors?

Evening Guys and Gals, just a couple of questions regarding PPIs & drinking.

I went ahead and bought some Tums and Prevacid (Lansoprazole). Tums did fuck all and I started my Prevacid regimen this morning and for the first time in a week zero heartburn. I dont wanna have to deal with DT so I took some Alprozalam but I only had 1 mg available. You guys think I'll be okay with a couple of night caps to help me sleep? I do plan on completing the Prevacid regimen but is a couple of shots is going to make the Prevacid pointless?
