I don't remember when I started using a CPAP (around 15 years ago), but it made a significant difference in my life from the first night. I averaged over 12 hours of sleep every day for the first month. I was incredibly sleep deprived!

I have a full face mask from Resmed, and have learned that dealing with the leaking means 2 things to me. First, I make small adjustments, both to the mask itself and the headgear velcro. The second thing I sometimes struggle with is getting a fresh cushion every month. I have a hard time coordinating with the store hours. One thing the sleep doctor said is to use a facewash every night, as the oils in our skin cause the cushion to deteriorate quickly. Getting a new cushion every month has helped a lot with the leakage.

I have only taken my mask off a few times, when I had panic attacks. I could put it back on when the attack passed. I even wear it for naps, whether I sleep or not. I strongly recommend perseverance in getting used to your CPAP. I can attest to the fact that it could change, or even save your life.
