Weight Loss Advice

Don't feel bad. You're down 165 pounds and maintained that level for a year. That sounds good to me.

A couple of things stand out from your post:

"try to log everything"

As Yoda says, do or do not. There is no try. Always log everything, even if you're going well over.

"snacks at night"

Healthy snacks I hope. Cutting out late snacks, and drinking more water to help feel full, is an easy way to lose calories.

Are you trying to do more exercise?

Basically, your problem is not logging dinner and then snacking and not logging that, either. It’s really easy to move from losing weight to maintenance calories with just snacks, so while I’m typically not someone who advises no snacking, your best option for now might just be to brush your teeth right after dinner and not snack, or have the only after-dinner snacks allowed to be raw veggies (no dip). Once you get back in the habit of accurately logging your dinners, then you can try adding snacks back into your evening routine.

OK, You forget to log dinner and late evening snacks : Put an alarm on your phone (or whatever device you prefer) to start remembering to track these. Roughly 200-300 calories can make the difference between losing and maintaining weight...

Before dinner: Consume something that has a high water content. You know how soup is like the "first course" of a fancy meal? Yeah.. use that... it will help you reduce the total calorie intake at dinner by making you feel full faster.
Or just drink tea or something else that is 1) Warm and 2) Basically just water.

Snacks: Keep them below 200 calories. Always.

If you know you tend to consume most of your calories in the evening - go lighter during the day.

I myself also eat more at the end of the day - so I basically do "intermittent fasting" by not eating in the morning and waiting till noon.
If you're one of those that believes "breakfast is the most important meal" then make sure that breakfast is actually healthy -i.e. if you tend to have a sugary breakfast (cereal, pancakes, waffles, and the like) then DON'T eat breakfast. You're basically starting your day with just sugar.

Food labeling guidelines allow up a 20% "error margin" in calorie counts on food labels... so products can state they have 120 calories but actually have 140. You can calculate more accurate calories from the nutrition label by remembering:

• Fat has 9 calories per gram
• Carbs have 4 calories per gram (remember to subtract dietary fiber - as it digests differently)
• Dietary fiber has 2 calories per gram
• Protein has 4 calories per gram

Fun Fact: the Food Pyramid originally released in the U.S. was ruined by capitalism (For example: Wheat products was moved from near the top of the pyramid (with a serving suggestion of about 3-4 servings per day) to the VERY BOTTOM of the U.S. pyramid with a serving suggestion of 6 - 11 servings per day!!!) - they were warned the changes they made would cause obesity, and sure enough where is the U.S. today?
I highly suggest looking up the food pyramids released in European countries...
Germany's food pyramid literally has WATER as the bottom layer.

So be aware of the fact that the U.S. government has never had your wellbeing on their mind and be careful where you source you nutritional information from.

Yep, you've got to log dinner. A lot of times we "forget" to log a meal because we know that if we log it, we'll be faced with how many calories we over-ate, and we don't want to see it. Also remember, it's possible to cheat your surgery and stretch back out your stomach if you consistently over-eat, which would seem a really sad waste of what was a genuinely serious, life threatening surgery. You've done well losing the weight you lost, and now it's time to get serious again with managing and tracking what you're eating.
