Not particularly much of an effect either way so far. Today is day 7 btw. Part of me not noticing too much is that i've also got an 8 months pregnant wife, and have spent the last 3 days cooped up in the house working from home since my 3 year old has been running a fever over 100 (so daycare won't take her). Actually thinking about it, over the weekend while I was out and able to see some eye candy, libido was a little higher than average
