You are a lab assistant. You have been hit with an energy beam and now you cannot
  stop growing. You have grown to six feet tall and  weigh over 300 pounds
You say "help me!"

 but the Doctor does not respond, he just stares at you in disbelief. He then
 turns around and walks away.

> You feel your clothes become a little tighter from growing.


Your skin tight clothing is starting to feel like it is squeezing you more tightly
 as you grow. Your chest begins to swell up and you begin to feel very uncomfortable.
 The shirt that you were wearing feels like it is about to burst open

> You look at lab ray settings.


You quickly turn off all of the lights in the room and try to remember what the
 settings are for the lab ray. You don't know how long you spent looking through
 them, but when you finally do find one that works, you press the button.

The light suddenly goes out

> You the ray hits you, but makes things worse.


The ray hits you and you scream in pain. It hurts so much! You fall backwards
 on to the floor and start to cry.
"What the **** happened?" you ask yourself.
"I... I don't know..". the Doctor says.


> You start growing even faster, a foot every five minutes.


You continue to grow rapidly, your legs becoming longer and your arms and torso
 becoming larger. As you get closer to the size of a large dog, you can see the
 Doctor staring at you with an expression of horror.
"It's working..". he says
You say "What do you mean it's working? I'm still growing! I'm getting huge!"


"Yes, but you're also losing control over your growth. In fact, you're gaining
 control".


> You try to slow down your growth, but fail.


You stop your rapid growth by stopping your breathing. You take deep breaths
 and exhale slowly. You feel your body slowing down and your muscles relaxing.
 You start to calm down and realize that you have lost control of your growth
 again.


> You feel your clothes tear as you rip out of your shirt and pants, left only
 in your underwear.


You feel your clothes tearing apart as you rip them off leaving you naked. You
 gasp as you let out a yelp of surprise.
