Tylenol is not that good for that kidneys long-term and is not recommended for daily use, but you're not on that much. I wouldn't worry right now but, long-term you might consider other options down the line is your pain gets worse and you find you're taking more pills more often. There are many people on way more then you are.

Narco is the same as lortab with less Tylenol. You can get hydrocodone without Tylenol, but it's not as effective.

I wouldn't worry too much right now as you're not on a lot. I wouldn't get freaked out about the lortab or the fioricet. Doesn't sound like you have that many headaches. If things get worse down the line, you might consider changing medications too long acting opiate. But that is for round-the-clock use and it doesn't sound like you need that so why even get into that at this stage.

I really don't think you much to worry about, but it's good to know that Tylenol isn't totally harmless to the body the way people think it is.
