CenTX I wish we had an active thread for all our posts on "what should I do?" when we get to the phase you are at.
I had all the same thoughts and questions and can relate. I got quite a bit of help on the Maintainers thread of you want to post your question there also.
Two thoughts of my "two cents".... as a newbie padawan in maintenance
1. On the area specifically about food and weight, physical health:
I am 5'7", my original goal was 160, I changed it part way through P1 to 149.
Same as you, couldn't get way from about 158/59 for about 3 or 4 months, very slow losses, but continued losing inches. Sometimes would go down about .5 lbs every few weeks, lots of up and down fluctuation of a few lbs during that.... similar to you found myself doing "cheats" that felt like came from starvation - for me the cheats were adding IP packets - finally around 156 just knew I had to phase off.
I did get down to a 155 goal, I have seen 151 on the scale and I have seen 158, but generally I am between 154 and 156 pretty consistently. Also I have built muscle so I continue to lose some inches while maintaining the weight.
Of course I have the desire to see 149, but every time I try to cut calories below my maintenance range of about 1700 net, my body rebels and I end up eating the extra calories at night. I am working out fairly intensely.
I realized this morning that this mentality is pretty stupid to some extent I think. I have my MFP type tracker set at 1420 calories so that I can lose a few more pounds, so every day it tells me in red I am around 200 over. This has been a month now. So I had to laugh at myself and realize that actually I have been successfully maintaining 153 to 158 and my body is consistently eating the calories I need to maintain it.
I told myself I would wait 9 months before I did more than a day or two pf P1 reboot. So my goal this weekend is to just be at peace with where I am, and continue to focus on my muscle toning and maintaining. I just changed my tracker to my maintenance calories

2. On the area of the mental aspect:
I am starting to see more and more where I use food to establish some kind of control in my life, esp. over stress or feelings that make me uncomfortable. I have a perfectionistic streak, and have chosen food and body as one area I feel like I can have control over. I notice that not having something to "fix" or control in this area bothers me, and I want to have something to focus on, and I question whether (aside from many actual health problems, which many of us have discovered or are discovering in the last few years of our journey) there was some kind of partial sabatoge that went on just so I could keep a hold of this safe area that I wanted to focus on. Like somehow I just didn't want it to work, I didn't want to just be "OK" - like an attachment to the suffering of it as a kind of comfort mechanism. Also if I noticed myself bothered or agitated about life, my mind wants to just focus on my body or health, because that is something I personally can fix, and maybe if I fix that the uncomfortable feelings will go away.
Anyway I know I don't have to figure it out of have a mental mindspin about any of it, and I didn't even like just writing that last paragraph, as it bugs me to face those areas, but I keep forcing myself to, because every day in the last year I feel better in all areas and am grateful to see my mechanisms that cause me suffering. Once I face them I can correct them.
p.s. Well guess what when I entered my 155 goal weight etc. and did the calculations my calories to maintain are about 2000, which is over what I have been averaging, so all my mental negativity has been no point whatsoever it turns out
