6 months! HELP

In June, I stopped using regular shampoo and conditioner. It took a while for my very greasy, fine hair to adjust, but after a month or so, I had stopped washing my hair daily and was loving my new, poo free hair. In the last month, I started a new job and started commuting an hour both ways daily. I don't really know if I think this has anything to do with the demise of my beautiful, grease-free hair, BUT I need advice. I have been pre-mixing my baking soda and water in an old coke bottle for a while. In the last few weeks, the baking soda water has no impact on the grease on my scalp. Like none! I've made super potent baking soda water and a more diluted version too. It's like my scalp is immune to the baking soda! When I'm washing my hair, my fingers don't get slippery like they once did. After washing with the baking soda solution, I use an apple cider vinegar solution. I really don't want to give up on no poo! Up until a few weeks ago, I was constantly bragging about how awesome my hair was even though I wasn't using shampoo. BUT I can't keep going to work with a mop head of grease!! And I'm not willing to sacrifice my sleep to take a shower in the morning. HELP!! Any advice is appreciated!
