6y2 - 13y + 6

(6y + 3)(y + 2)
(2y + 3)(3y + 2)
(2y - 3)(3y - 2)
prime

I've read a lot of the answers about crushing pills but I had another question or two. I take about 35 perscription medications each week and a lot of the bottles say do not crush or chew. On the bottles that do not say that, is it safe to crush those up and mix them with food? A lot of the pills just dissolve on my tongue and taste horrible. I also have sudden severe headaches and a lot of the time my vicodin or tylenol3 takes forever to work. I wondered if crushing those would increase the speed that my system metabolizes those pills. I know there's a danger when crushing any pill that you'll receive too much of the dose at once (especially with time release pills like ambien or lunesta) but is it something that will cause serious health issues or just something to be wary of and only do occasionally?

My dad was a perpetual thermostat Nazi, so I grew up getting used to sweating at night in 78 degrees temps and utterly freezing in the winter with the thermostat down to 64.

Now my husband complains because I am used to these temperature settings but he is not, and we get in fights over it. His dad was one of those thermostat Nazis too. But now he says "I earn the money, I pay the bills, and if I need the thermostat set to 72 at night so I can sleep, that's how it has to be!"

The problem is, now when he sets it to 72 at night in the summer, I'm freezing. Or when he sets it to 72 in the winter, I'm dying of heat.

He also complains that my body temp goes up 2-4 degrees every 4 weeks... PMS hormones... he says "You're thermonuclear again!" and hits the thermostat down... and then I'm freezing.

But I don't know how to answer him when he hits me with the simple logic: why is 72 in the summer "too cold" while 72 in the winter is "too hot"?

Why does it feel that way?

I think we just had a random boom of static electricity. My lights wavered a bit, never actually went OFF... but my computer did, came back on to the same spot it was in, but I turned it off anyway.

I hear a couple car alarms.

Wtf was that? It made no noise, there's no lightning... it IS humid outside due to some rain earlier...

was it a random boom of static?

I'm kind of scared.. I'm in TN btw.
