Thought I might share some flaws (see Unearthed Arcana) that I've used for a few characters of mine.
Also, if you have any flaws you've written, feel free to post them here and I'll make a list.
\_ \_ \_ \_ \_ \_ \_ \_ \_ \_ \_
You require 2 more hours of sleep or meditation than others of your race to function properly and take a -2 penalty to saves against sleep-based spells and abilities.
Night Terrors [Flaw]
Your sleep is constantly beset by intense nightmares. There is a 20% chance every hour that you sleep that you awake screaming. Upon awakening at any time you are considered Shaken until you have been conscious for 1d4 hours.
Your mind becomes so hyperactive while unconscious that you spend the night sleepwalking. A sleepwalker can take simple actions such as moving his base speed in a random direction or picking up objects. You are considered flat-footed, and take a -20 penalty on spot checks so that though you are unlikely to walk off a cliff, you may not be able to find a doorknob to let yourself out of a room. You are not consciously aware of your actions. You can be awakened with a swift shaking or sudden loud noise, though awake automatically if you sustain any damage.
Whale Dream [Flaw]
You are a member of an aquatic race with especially strong emotional ties to the water. If you do not submerse yourself in a natural body of water at least one per day you take a -1 penalty to all attack, damage and save rolls until you do.
World Weary [Flaw]
You have seen much in the world, leaving you with an abnormally heavy heart. You gain only half the benefit from morale bonuses (minimum 1). As well, you take a -2 penalty to saves against Crushing Despair and other like spells and abilities.
So hero feast for breakfast lunch and dinner, and you can't be shaken. Thus, Night Terrors is the perfect flaw for fighters.
Unless you use the suggestion again of bypassing immunity, of course. And it not being cured even by magical healing. And with drowsy, it's not really a flaw again if you have a ring of sustaining or one of those sustaining ioun stone thingies.
Well, Nobody's Perfect [Flaw]
You no longer benefit from natural 20s. All 20s are treated as normal 20s and you may not threat critical hits from a roll of 20. You do not roll additional dice or automatically succeed.

That seems, well, really powerful. No more critical hits?
I don't get it. So if a fighter has 20/x3 weapon, he becomes unable to crit? If he has 19/x3 weapon, he threats on 19 but not on 20? Seems rather wierd... Would rather just put "20 is not auto success" but keep everything else fine. The current way it is quite confusing and block crits from many builds.
Then again, without the crit thingy it would not be worth anything as in most cases 20+mods is high enough to succeed in stuff anyways. :/
EDIT: The rerolling 20s might actually be a good flaw.
Can't Hit Hard [Flaw]
Through either hesitation, lack of skill, or sheer bad luck, you find it difficult to land a telling blow.
Prerequisites: Proficient in all martial weapons.
Effect: Reduce your critical threat range on any weapon you wield by half, rounded up. Thus, an 18-20 threat range would only threaten a critical on a 20. If the weapon's threat range is 20, you may not score critical hits with that weapon
Your savagery oftentimes distracts you in combat.
Prerequisites: BAB +1
Effect: Whenever you kill a creature in combat or knock a creature unconscious with a melee weapon, you must spend a full-round action next round mutilating the body or reveling in the victory in some other way. If you felled the creature with some other attack, you must spend a full-round action the next round moving toward the felled foe. You may choose your route, but only if you end your turn as close as possible to the fallen creature.
Zoological Obsession [Flaw]
You are obsessed with a type of creature and cannot bear seeing one come to harm.
Effect: Choose a type of creature, such as humanoid, dragon, or abberation (Subject to DM approval). You may not deal lethal damage against that type of creature or attempt to harm them in any way (Includes ability damage or drain or any magical effect that does not include "harmless" under its saving throw). If you unintentionally harm one of these creatures, you are shaken for an hour. This effect bypasses fear immunity.
Additionally, if you see a creature of this type die, you take a -2 morale penalty to all attack rolls and saving throws for 24 hours.
I need to figure out better titles... suggestions for this one?
Whenever under a situation that would cause stress (fear, combat, etc), you wet yourself. This can cause clothes not washed to get fungal growths, and can also cause dehydration if done more times in any 24 hour period than your constitution score (see rules for dehydration in the DMG).You cannot have an accident more than once per minute.
