Psycho (Fallout)

Characteristics
Interestingly, psycho has another effect not intended by the programmers. When taken, it reduces Intelligence by 3. This can be exploited to boost your skill points. First, raise a skill to the point it needs two skill points to be increased, then level up. When you level up, take two to reduce your Intelligence greatly. This will correspondingly lower your skills involving Intelligence (Science, Repair, Outdoorsman, Doctor, etc.). Now allocate your skill points to the skill you want raised - since the skill's value has been lowered, it will take only one skill point to do so. Then rest for a few hours. When the psycho wears off, Intelligence will be restored, and the skill will be given a significant boost. This is particularly useful for getting a 121% science skill to recruit Skynet without taking Mentats or wasting too many skill points.
