Need more alcohol than I can stomach to get drunk? Help

Hello, I am a uni student in Canada so I do a fair bit of drinking etc. etc. Lately, while I have gained alcohol tolerance in the sense that I need more to get drunk, I have lost alcohol tolerance in the sense that I throw up earlier. This puts me in a weird spot where I throw up before I achieve the drunk that I would like to. Has this happened to anyone before? Any tips for dealing with this? thank you in advance.
