My understanding of the ip/up suffix is that it is used when you have the same subject (in this case Ahmet) and two separate actions (taking a shower & sleeping)

I hope this helps you understand. 

Right! Forget about the diets! Just stick to some practical guidelines:

• Eat slowly, it takes time for the brain to think you have eaten enough.
• Drink water before the meal and don´t drink it when eating. Drink 1.5/2 lts of water a day and drink it along the day.
• Eat more veggies. At least one main course should be veggies. It takes 2 hours to digest veggies compared 4 hours for meats. veggies have less calories and keep you filled longer
• Eat fruits in small portions. Half of a banana, a small apple for example.
• Do not eat sweets more than once or twice a week and prefer light ones like "sütlaç" "muhallebi", "kazandibi" etc.
• Take fats moderately. 4-5 spoons of olive oil a day should be enough.
• Don´t give up eating carbonhydrates. 60% of daily intake should be carbonhydrates.
• Do not eat late. You should have your dinner by 1900.

Quoted from: here

4 Large Potatoes (cut into cubes)

1 green pepper (roughly chopped)

1 red pepper (roughly chopped)

1 medium onion (roughly chopped)

4 large tomatoes (skinned and diced) or 1 can of crushed tomatoes

2 teaspoons of caraway seeds

2 teaspoons of paprika

2 tablespoons of olive oil

Salt and black pepper to taste

In a large saucepan, brown potatoes in olive oil and cook until all sides are brown.  Add peppers, onions and tomato, caraway seeds and paprika.  Salt and pepper to taste.  Simmer uncovered until all ingredients are soft.  Serve as an entrée or side. 

(I like to top mine with croutons)

"alıp" is used here as a gerund. one could say "aldıktan sonra". Both have same meaning.

al - mak , al - ıp (aldıktan sonra)

uyu - mak , uyu - yup (uyuduktan sonra)

yat - mak , yat -ıp (yattıktan sonra)

on themselves or on other people?
