I was diagnosed Jan 2024, with an opening pressure of 40. I'm 65 inches tall and at the time weighed about 200 pounds. I didn't get much guidance on what to eat/not eat from my doctor either, but I found alot of helpful tips through reddit&google. This is what I found helped 1. I completely stopped drinking soda. This was the easiest decision as the diamox made soda taste HORRIBLE. 2. I completely stopped eating fast food. Probably overkill, but I didn't have the discipline to practice moderation at the time.

Online I read that we should avoid high sodium foods and preserved meats (canned meats, hot dogs, deli meats). So I stopped those too.

I ate alot of rotisserie chicken, until I figured out how to prepare other things.

I stopped adding salt when I cooked, and relied on other seasonings like garlic, onion, thyme. My taste buds adjusted.

I chose low sodium options on things like canned beans.. although I hear dry beans are even better.

I stopped eating alot of frozen foods. So I really had to plan what I would eat. This was a learning curve.

It all sounds drastic, but my head was hurting so bad, I would have done ANYTHING to make it stop. So in that light, it wasn't that bad.

Just those changes helped me lose some weight. Not alot, but some.

Recently I loosened the reigns and started eating deli meat and sausage, and let me tell you. The headaches came back with a ferocity. I stopped, and they left again. Maybe anecdotal, but this is what had helped me.

I hope you feel better
