Answer

Yes, generally after doing regular Chovihar, you may drink water the next morning after the Chovihar period is over.

In Jain practice, Chovihar means not eating or drinking anything from sunset until the next day, usually until sunrise or the proper morning time according to your family/tradition.

Explanation

If you did a normal Chovihar last night:

• You should not eat or drink during the night.
• After the night has passed and it is morning, you may drink water.
• Ideally, drink clean, properly filtered/boiled water as followed in your Jain tradition.

If you had taken a specific vow, tapasya, or longer fast such as Upvas, Tivihar Upvas, or special Pachchakkhan, then the rule may be different.

Takeaway

For regular Chovihar, drinking water the next morning is generally allowed. If you are unsure about your exact Pachchakkhan, ask your Guru Maharaj, Sadhviji, or a knowledgeable elder in your Jain tradition.
