I take 80mg's of adderall a day (40 initialy, 20 4 hours later, 20 more 4 hours later). I've been drinking a ton of water (maybe close to 2 gallons a day) because of the dehydration it can cause. I get horrible headaches if I don't drink enough so I just make sure I always drink plenty. My question is, does drinking so much water result in the adderall being flushed out of my body faster (I go to the bathroom A LOT)?

EDIT: The reason I ask is because since I increased to this dose maybe a month ago, it hasn't been as effective this past week. It is still helping, yet the concentration isn't as good as it once was. I've also started drinking more water recently since I live in Florida and its started heating up. So I'm curious if the noticeable decrease in concentration is just from me adapting quickly or from my increased intake of water flushing the drug out of my system?

When I tried adderall, I was drinking about 3-4 liters of water from the beginning and it did work initially for me... My vote goes to no, the extra water shouldn't have an affect.

Thanks for the input.

I'm sure water intake doesn't have an affect on the effectiveness of the dose, but maybe it flushes it out of my system faster so instead of taking a dose every 4 hours, I may need one maybe after 2 or 3 hours?

Being new to Adderall, I haven't tested the effects on different intakes of water yet, but to add, I definitely have noticed HUGE decreases in it's effectiveness when taken with food. I'm still trying to figure out a way to use my daily dose of IR effectively. If I take it in the morning, I'll be focused during class, and then when class gets let out I won't be able to do a single homework/studying assignment for the rest of the day. And if I use take adderall twice a day, I build up tolerance to it almost instantly. So annoying...

Yeah I agree, I noticed that it just does not work with food. Only my first dose works because I take it before eating anything. Then I take my 2nd one about 2-3 hours after lunch and it feels like i took nothing. I avoid the citric acid and vit C too around the doses, and I only drink water. So since I sometimes have classes late, I tend to totally crash in those classes :(

its really hard to know when to time the doses, especially with the XR I'm noticing.

Short answer? No. It does not "flush" adderall out of your system. Your body is not a toilet. :)

BUT . . . too much water too fast can cause "water intoxication" (hyponatremia)

"Sodium is a key component of your body. It's an electrolyte and helps carry nerve impulses between cells. (emphasis mine) It helps maintain normal blood pressure, it's essential for your nervous system to accomplish muscle movement, and it regulates the fluids in and around your cells.

Normal blood plasma contains between 136 and 145 milliequivalents per liter (mEq/L) of sodium. Hyponatremia occurs when the sodium in your blood falls below 135 mEq/L.
When the sodium levels in your blood become too low, excess water enters your cells — causing them to swell. This swelling is especially dangerous to your brain because it's confined by your skull and unable to expand."

If your Adderall makes you feel so dehydrated you WANT to drink 2 gallons of water a day, talk to your doctor. You may need to replenish your electrolytes, not just drink water, to maintain the proper blood level of sodium.

I think what you are noticing is a reduced absorption rate; Adderall takes longer to be absorbed when taken with food. Overall you get about the same amount, but you flatten out the plot of concentration in your blood.

Yes, that makes sense. Takes a bit longer for it to be absorbed as opposed to one shot on an empty stomach.

Well, how it went with me was I took adderall, then had lunch immediately. In 15-20 minutes the adderall started working amazingly. Was more clear headed, was amped up, had more energy, was getting school work and chores done like crazy, and then in an hour it was gone...and back to the same old useless self. So I think it has a bit more to do with decreasing the effectiveness. UNLESS, if taken with food the adderall gets absorbed at such a slow and small rate, that it's not enough to even feel the effects from it.
