Question 1

when i have caffeine on levothyroxine even hours after taking my pill 100mcg i get the fogginess feeling ... how can i avoid?

Accepted Answer

You arent going to..: You aren't going to like my suggestion....Stop the caffeine.  Good question for the prescribing physician.  Might require a bit of research unless they are an endocrinologist and already know the answer.  Best wishes - a fellow caffeine lover.

Question 2

after how many hours are the nodoz (caffeine) going to wear off?

Accepted Answer

Half-life 5-6 hours: The half-life of caffeine is 5-6 hours, which means the amount in your blood (and therefore the effect) decreases by half in 5-6 hours. How long it works will depend not just on the half-life but also on the dose taken.

Question 3

i took 1 pill of vivarin (caffeine) 1hr ago & never felt the effects. it recommends takin 1 every 3-4 hours can i take another 1? how can i keep awake?

Accepted Answer

Vivarin (caffeine): Hi, I don't recommend that u take Vivarin, (caffeine) it has too much Caffein and it could harm u, especially with history of ur memory loss and insomnia.

Question 4

when i drink caffeine on levothyroxine, even after hours of taking my pill i get the fogginess feeling... should i cut all caffeine out?

Accepted Answer

That's Unusual: And i don't have a good reason to explain your situation, but i would try to cut out caffeine and see how you feel.

Question 5

why are some people abnormally sensitive to caffeine e.g. 1 can drink coffee b4 bed w/o prob but 1 is super hyper for 7 hours after drinking it?

Accepted Answer

Adaptation: If someone takes caffeine (or just about any stimulant) regularly, the body adapts and "gets used to it". There are detailed mechanisms that explain this, but the bottom line is if you haven't been exposed to caffeine or a related stimulant, you will have a much bigger reaction to it, compared to someone who takes caffeine regularly.

Question 6

is it better to take a caffeine pill or 5 hour energy?

Accepted Answer

For what goals? This: is the far more important issue. Both promoted for symptoms; cure nothing, may promote other problems, especially if used frequently.  Additionally there are so many individual differences + no organized prospective placebo controlled or comparative trails of any sizable group on which to base an answer. Thus usual self-experimentation/buyer-beware. Rec: Google: "sources of caffeine in nature".

Question 7

is it okay to take prescribed ambien (zolpidem) within a few hours of drinking caffeine?

Accepted Answer

Yes, but...: You are creating a rollercoaster type of behavior which suggests pending addiction.  The Ambien (zolpidem) won't work as well, plus, more and more reports of memory loss are coming out with Ambien (zolpidem) use.  Ambien (zolpidem) has been linked to date rape, sleepwalking, and even a couple cases of unremembered murder.  Please reconsider your actions.

Question 8

how many hours before my bedtime, should i stop drinking caffeine ?

Accepted Answer

Variable: Everyone handles caffeine differently, some people can drink caffeine and go to sleep promptly, other people are kept awake for hours. You will need to experiment and determine what works best for you.

Question 9

is 35 hours before a blood test enough time for one to drink caffeine before a blood test? i dont want to mess up my results bc i drank caffeine.

Accepted Answer

No problem: Caffeine has no effects on any blood tests. Drink as much coffee or other caffeine drinks as you like, right up until you are tested. It won't make any difference.

Question 10

why do i always pee much less, hours or 1 day after i have drank caffeine? it's about half the amount as normal, but it completely returns to normal.

Accepted Answer

Usually the opposite: Caffeine, which is a stimulant, usually works as a diuretic and causes increased urinatiion after consumption. If your urine output returns to normal you may do well to avoid caffeine all together. If you are unable or unwilling to abstain from caffeine and you are still having problems, you could seek eval by a urologist to assess your voiding.
