When you stop smoking, your body goes through nicotine withdrawal, which may cause symptoms such as dizziness, headaches, or a hangover-like feeling. These symptoms are usually temporary and tend to resolve within a few weeks. To manage them, drink plenty of water, rest well, eat balanced meals, and try light exercise to improve circulation. If your symptoms are severe or do not improve, please consult a doctor to rule out other causes.

Sleep medications such as melatonin or sedative-hypnotics like zolpidem may help you sleep better. However, it is important to consult a doctor before starting these medications, as some may cause dependence or side effects. Maintaining a regular bedtime, avoiding caffeine and heavy meals in the evening, and limiting screen use before bed may also help.

You should consult a doctor to investigate the underlying causes of your symptoms, which may include sleep disorders, digestive issues, or heart conditions. Try to eat earlier in the evening, maintain a regular sleep schedule, and avoid caffeine, alcohol, and heavy or spicy meals at night. Reducing stress through deep breathing exercises or meditation may also help improve your sleep, digestion, and overall well-being.

Persistent poor sleep with chest pain and red eyes is concerning and should not be ignored. Avoid caffeine and screens at night, keep a regular sleep schedule, and try sleeping with your head slightly elevated. Because chest pain can be serious, especially if it recurs or is associated with discomfort or breathlessness, seek medical evaluation promptly.

Establish a regular sleep and waking schedule and steer clear of screens, caffeine, and large meals at night. Before going to bed, engage in relaxation exercises like deep breathing or meditation, and make sure your bedroom is quiet and dark. See a physician if insomnia persists for longer than two weeks or interferes with day-to-day activities.

Without a doctor's assessment, I am unable to securely suggest a particular sleep aid for you, particularly in light of your medical conditions. Melatonin and other over-the-counter alternatives are occasionally used for brief periods of time, but you should first talk to your doctor about this to prevent drug interactions. In addition to treating the underlying cause of your sleep disturbances, your doctor can recommend the appropriate sleep aid.
