The main thing is while you are off- Try to get some exercise to keep the body in shape without straining the Knee and the ligament. Your upper body will lose a great deal of strength if you do not get some exercise. Suggest you lose the remote on the TV for a while- So that when you want to change channels you will have to get out of the chair and walk (Gently mind as you have a knee Injury) to the TV and change it manually. Another alternative is to Cut down to a small wineglass for the beer and leave the opened bottle in the fridge. Drinking three pints a night should give you about 12 trips to the fridge to refill the glass.
