I feel you lol and you See, that is what I'm definably "NOT", doing. I have a full time job as well and when I come home, sometimes I can beardy lift my pencil talk less of drawing. so I created a patreon page for my devoted readers, with that I put more effort regardless of how tired I am because I believe it's justified due to the fact that they are consistent in supporting me. don't get me wrong, I still cater to my free readers but not in the expense of my health. I only update twice a month with each update being at least two pages and I like it that way. with that being said I'm not stressing because if I miss an update then they will just have to hang on until when I can post.
I love what I do, however given the fact that I don't have that much time I try my best to practice better time management. so with that being said, it's up to you. if you can post once a week then go right ahead if not, do as I do. but the chances of that is, you risk a chance of getting inconsistent readers and postally undevoted fans.
