You really need that PhD before you get the more interesting jobs, especially if you want to avoid becoming a code monkey.

Research is fun and interesting (as well as dangerous and more often boring). Problem is it is badly paid.

I guess it barely rotates given the large magnitude of lamina.

It rotated for 0.0358 of a revolution or 0.225 rad if I didn't screw up like I always did in my homework.

Hello, /sci/, need some help from biologists or medical students.

How do I quit sugar without getting extreme tiredness? If I quit sugar, I get headaches the next day/two days after of an extreme nature and my sleep goes to shit (literally 12-14 hours of sleep).

What is causing this? Does increased sleep cause a crash of serotonin resulting in an endless cycle?

Do I have blood-sugar problems? If so, does that mean going cold turkey on sugar is actually a bad thing? Are people with blood-sugar problems unable to readjust sugar levels to normal?

Is exercise and a proper sleep schedule the best way to re-balance this?

I've also been suffering from stomach/intestinal problems a lot recently. I hear serotonin is produced in the gastrointestinal tract, so does that mean my diet is having an affect on my neurotransmitters and affecting my mood/sleep?

Just fucking fast dude, literally stop eating for a week and drink lots of water. Do you have an appetite? If not, it's possible your body is trying to fast but you keep stopping the process from your addiction.

Fasting is like the greatest thing for curing random shit.

>>8934768

Then when you are done eating start eating healthy (plant based diet, not a lot of carbs). You know how there is a fruit section as soon as you walk into a grocery store? Eat shit from that section.

You do it gradually as you would with any given drug, because at such quantities that is what it is.
A pill for headache will help.
After detoxing yourself take a blood test and find out if you already have diabetes.

I have an offer (CS undergrad) from 60 (TU Munich) and 8 (ETH), but for the ETH I would have to write an (expensive) test to be admitted and pay shitloads of living costs for Zurich.

What do?
