Can Drinking Impact BBT?

Nikki
This is my first month charting and I feel like my chart is all over the place. I have very long cycles (45-50 days) so I am pretty sure I have not ovulated yet. 
That being said, I have had one or two drinks a few days this month. In studying my chart I think I'm seeing a rise in BBT on mornings after I've had a drink (dark green boxes in screenshot line 01). Should I be discarding temps those days? I'm done drinking for the month so hopefully my chart will be less eradic.
