It takes time to get stamina back. It requires exercises on most days of the week. Drinking is not healthy especially if you do sports.

Gaining Stamina is a aerobic process and so to see effects could take weeks. Exercises like exercises long in duration but medium intensity should help stamina. This could be a jog but would have to be minimum of 20 minutes otherwise it may not help stamina as it could mean that you are working speed and power instead.
