Cold with nasal irritation

I am 26 year female,I frequently get cold since last 4 years.
Frequent cold due to climatic changes . symptoms are nasal  irritation especially at night or as i lie down the nose feels blocked suddenly ,....a lot of sneezing with watery nose....
    another problem comes from INDIGESTION  which also gives me a bad cold...i get a lot of burps and then a lot of sneezing including watery nose...
  i experience nasal irritation almost everyday and cold conditions prevail for 3-4 days only to return again after weekly gap.
 the climate is cold here especially at nights and it stays windy the whole time.
I ll be very greatful if anyone help me in getting cured.I am not able to concentrate on my studies due to this. Sometimes I feel so lethargic,that I don't feel like doing anything.plz help me

Sulphur 30 c( three times a day for a week)
Belladonna 30 c( three times a day for 
a week )


I hve just moved from a warm to a cold climate place so i believe my body is not able to get adjusted to this weather change.since  Nasal Irritation;  its alwaz windy here my nose picks up sudden irritation especially at nights.i feel cold is accumulating on my nose which enhances the irritation and leads to heavy and repeated sneezing accompnied by watery discharge which is too much. i go on sneezing for a couple of hours  which gives me a dizzy head .i feel loss of control over my body and mind  and go completely lethargic.also to mention a night before i fall sick like this my body temperature rises while in bed and i start to sweat abnormally and the following day catch the cold and i stay sick for 3-4 days.
   INDIGESTION.  There is another way i catch cold which is indigestion which might be an allergic reaction on my body.sometimes  my system feels upside down especially after consuming milk or anything in liquid. i start to get repeated burps which makes me uneasy and piuqish    WATERy DISCHARGE.then there is a lot of sneezing accompnied by watery discharge. it stays for 2-3 days to feel any normal.i hve been hving this problem of indigestion for past 8 months.
