Bhai Vitamin D sachet start kiya, 5 din mein thoda light feel hua, but joint pain aur pet kharab ho gaya. Kya yeh sab normal hai?

Yaar, finally last week I started taking those vitamin D sachets (60k IU wala) jo doctor ne prescribe kiya tha. Honestly, 2-3 din toh kuch fark nahi laga, but aaj 5th day hai and I feel a little less tired. Thoda light lag raha hai body mein. But still woh joint pain hai especially knees mein, morning mein uthte waqt bohot akad hoti hai.

Mera B12 bhi low hai, toh doctor ne injection diya hai 2 weeks mein lene ko. But yeh sachets ka taste toh bohot weird hai. Pani mein mix karta hoon toh kuch zyada hi zyada effect nahi hota. Kya koi aur bhi face kar raha hai yeh? Aur mujhe pata nahi kyun, lekin inke saath garmi lagti hai, pet bhi thoda loose ho gaya.

Ghar mein amma bolti hain "dawai kyun kha raha hai, dhup mein baith". But office se aata hoon toh 7 baje, tab tak dhup nahi hoti. Weekend pe bhi ghar mein hi rehna hota hai. Thoda frustrate ho gaya hoon.

Mera question: Yeh sachets actually work karte hain? Kitne din mein result dikhta hai? Aur kya side effects jaise acidity ya pet kharab hona normal hai? Please share your experience.
