Obviously, asanas and pranayama alone are not going to help comprehensively. You need to change your life style, diet, and your attitude.
Life style should be early to rise in the morning and early to go to bed at night, avoidance of beverage product, following the yama and niyama - personal conduct and social conduct, surrendering to God.
Diet should always be sattvic - fresh, and vegetarian - easy to digest. It should not be non-vegetarian. Alcohol should be strictly prohibited.
Attitude should always positive. If your attitude is negative, the energy you generate through your sadhana - asanas, pranayama and meditation will go in that negative direction. So beware of negative attitude, negative thoughts otherwise, you will not be benefited.
