Can’t handle alcohol after abstaining.

Hello, about half a year ago I had a pretty serious problem with alcohol consumption, and have decided to put a lot of effort into abstaining. I am now slowly trying to get back to casual drinking and similar. However my body absolutely rejects alcohol now, just a single shot of vodka or rum is enough to make me want to vomit my insides out. I cannot even stand wine anymore. Is this normal and will I ever be able to enjoy drinking again? First time poster
