Please don't force yourself to stay awake if you are feeling exhausted, your body is telling you to rest. Try to eat small, frequent meals to keep your blood sugar steady, and go for a gentle evening walk to get some fresh air. Take care of yourself, this phase will pass very soon.
My mother-in-law used to suggest drinking warm milk with a pinch of cardamom to feel refreshed, which did help a bit. But my doctor said the sleepiness is just progesterone working, and it's best to sleep whenever possible. Listen to your body and rest well, dear.
Fatigue is super common because your body is working overtime to grow a whole human. Try to take short 20-minute power naps during the day and stay hydrated. Also, check your iron levels with your doctor, as low iron can sometimes make you feel extra sleepy.
Oh, I feel you, I was a total zombie during my first trimester! Honestly, don't stress too much about being lazy or unproductive. If your body wants to sleep, just take a nice nap and let your husband handle the chores for a change!
Honestly, a nice cold glass of fresh orange juice or some sour aam papad always wakes me up instantly! When I feel super sleepy, I just have a light snack and it gives me a quick burst of energy. Eating small portions throughout the day definitely helps!
