Need a relieving remedy for cold, cough, nasal discharge etc

Dear friends,

I have been suffering from cold for the last few days. Severe coughing (sometimes yellow expectoration or else dry), nasal discharge (yellow from both nostrils), troubled breathing, both nostrils open now, previously one of the two nostrils would be blocked from breathing and open up, sequentially, troubled speaking and mild hoarseness.

Nasal discharge and expectoration starts after morning wake up and continues multiples times throughout the day until I go to sleep at night. Feels better after morning bath. Severe coughing before sleep at night. Love to remain in bed for rest. Previously there was headache but not now at the moment. No expectoration currently and strong dry cough. Have constipation. Normally easy defecation in the morning but because of cold, there would be no urge for bowel movement in the morning but strong urge for defecation in the evening. The amount of stool is less than that it would be normally. Today not having problem sitting under ceiling fan air. Previously would feel chilled and cold when the air from ceiling fan touch the body.

I am able to have my regular meals everyday in the right amounts or volume and also drink plenty of water everyday. The local homeopathy doctor once gave me bryonia 200 (liquid soaked in white
round pellets in a very small bottle), 10 pellets 3-4 times a day and that worked just fine. Will I still take bryonia 200 under such symptoms? Or any one of you could suggest a better medicine since I am suffering heavily from the above-mentioned symptoms.

Thanks in advance.
