If you are diagnosed with hypersomnia, your doctor can prescribe various drugs to treat it, including stimulants, antidepressants, as well as several newer medications (for example, Provigil and Xyrem).
You may have your 2015 RMD made payable directly to the charity (provided it meets the IRS definition of a qualified charity), and then designate it as a qualified charitable distribution on your tax return. You'll have satisfied your distribution requirement, and you won't have to pay income taxes on that money.
Distributions taken late are taxed at the rate of 50%, whereas the account owner can elect the tax withholding rate for RMDs taken on time. RMDs are partial annual payments required by the IRS. The rule is in place to ensure that retirees actually withdraw from retirement accounts rather than using them as a vehicle to pass money to heirs.
