What should I do if I feel intoxicated at a depth of 33 metres/110 feet?

Feeling intoxicated at a depth of 33 meters (110 feet) can be a serious situation, as it may indicate nitrogen narcosis or other diving-related issues. The correct course of action is to ascend to a shallower depth. This is because the effects of nitrogen narcosis, which can impair judgment and coordination, are typically less severe at shallower depths due to reduced ambient pressure.

By ascending, you can alleviate the symptoms of intoxication. The nitrogen bubbles in your system are more concentrated at greater depths, and by moving upwards, you reduce the partial pressure of nitrogen, which helps your body metabolize the nitrogen more effectively. This step is critical for ensuring your safety and minimizing potential hazards associated with impaired cognitive functions underwater.

Continuing the dive slowly, taking deeper breaths, or staying still until you feel better do not address the immediate need to manage the detrimental effects of the depth on your physiological and cognitive state. Instead, ascending allows you to escape the impairing effects of deeper waters more safely.
