You are still drinking, so no, you are not helping yourself with the cycle of drinking/not drinking. It's binge drinking.
I think quitting cold turkey is the way to go. You won't feel miserable for long. Certainly not long enough to impact your studies.
To put quitting off until you get back home is just an excuse to keep drinking.
