TTC on hold advice

So my DH and I have been TTC for 2 months now, with no luck. Unfourtanelty though we won't be able to start trying again until April. DH is having surgery this month and will be in recovery until then. I was really hoping to have a BFP this month but I guess it's for the best. Anyway, I was wondering if I should still be doing the same things if I were TTC. For instance keeping a low caffeine intake, no alcohol, ect. Or since I'm not TTC these few months it doesn't matter? Any advice would help :) Thanks!
