INR too low

Hi... I've been on warfarin for nearly 2 years following having a mechanical heart valve. I had a bicuspid aortic valve. My INR target is 1.5 - 2. I have never been particularly stable but did have a period of 6 weeks without a test earlier this year. Just lately I have been taking more warfarin but INR going down. Last test was 1.2!! down from 1.7 4 weeks earlier. My dose is now 5.5 mg 6 days out of 7. I was given 7mg last Tuesday to get it up quickly.
Does anyone have any ideas why it is going down rather than increasing? I even stopped eating broccoli and avocado.
I have recently started the keto diet (about 3 weeks ago) could this have an effect?
I do drink alcohol at the weekends. Perhaps I should drink more to get the INR up!!!
