You can do a some things to minimize the withdrawal symptoms.
Get a Mineral Deficiency Test. - With this, you will know where you need to improve nutritionally. By ensuring that your are nutritionally, satisfied, your body will not crave for nutrition, and hence make it easier to break from an addiction. The body could be asking for nutrition, while you are feeding it with substance that has little or no nutritional value.
Get plenty of regular exercise. - If your daily work does not give you exercise, you will need to create time to exercise. Exercise is not an option, but a necessity, without which the body and the organs weaken. There is a direct link between the clarity of thought and a healthy strong body. With a healthy body and mind, you will be in a better position to fight the current addiction, by persevering and being determined to overcome it, as well as resisting any new addictions.
Get enough rest. Sleep at least 8 hrs, 9 is better.
Drink water all along the day. Keep your body well hydrated all throughout the day, this will keep your body functioning optimum at all times as well has help detox the system. If you do not have access to a water dispensary throughout the day, you may need to begin carrying with you water bottles. Ensure that you are drinking filtered water.
Replace the bad with the good. If the tea that you were drinking was healthy tea, you should not be having withdrawal symptoms. Your symptoms sound similar to those who were withdrawing from coffee (caffeine - google the harmful effects of caffeine). I would not be surprised if the tea that you have been drinking has caffeine. You can replace that tea with healthy herbal tea. You can choose from a whole variety - they too got some variety with good aroma.
Also try to minimize the use of sugar or completely replace it with a healthy alternative, such as honey.
