I eat lunch at about 1pm and don't get in the water till 330.

have you been consistent with core workouts or are your abs out of "shape"?

i have trouble being calm with my breathing and when i do i cramp up (legs but it's still a cramp)

Are you swallowing a lot of water? I have found that if I "accidentally" swallow a ton of water while I swim I cramp up. Also, I tend to swallow a lot of water after I have taken a small break from swimming because my form has begun to deteriorate slightly.

I found this on a medical site and it explains my problem exactly. However, I can't figure it out, maybe im just tired, but I see the problem laid out but I don't see a solution..
Any tips after reading it about what I should change to fix the problem?

When you are swimming at a casual pace your breathing is measured and usually goes in/out the same depth via the mouth . Air breathed via the mouth moves up into the lungs via the asophagus and fills the lungs to capacity. If your breath is larger than the lung capacity, this excess air still being breathed in goes into the stomach . When you release the air at the end of respiration, lung air is released before stomach air. Excess air in the stomach is belched out or moves along with food into the intestines. Normally it is a small amount of air and gives no problem. When you swim at an increased pace over a longer period, or in a panic state such as with racing or just pushing yourself, then your breathing becomes uneven and gasping. You may skip (hold) a breath in order to give yourself more time to pull yourself through the water. This time increases swimming speed. When you take that breath , you will breathe in great gulps of air at one time and then blow it out at a slower pace. When you gulp air, that air goes into the stomach with each breath and instead of moving into the intestines with food processing, it is pushed out of the stomach into the intestines without food because it has no where else to go; you need more space for incoming air. The air becomes a "bubble" moving along. Because there is no food, there is little bacteria hanging onto it to break it down into smaller pockets of air as it moves along the intestional tract. With great bubbles, the intestines expand or distend to allow the air to move along. Your stomach seems a bit firmer or harder to the touch, you feel bloated, which can be painful , until the air is either released from the rectum or is reduced in size from residual bacteria in the bowels . This can take several hours. As long as the manner in which you breathe during swimming continues, the problem will persist. Hope this helps

Are you taking large breaths? I think cramps are caused by A) too much air and B) swallowing too much water. Work on taking smaller breaths.

and pee!

OH MY!

Precisely.
