6 months now - Watery running nose, very strong sneezes, frequent mucus discharge

I am 32 M, and have been the following problems for the past 6 months now. It started with Cold and Cough for which I took Bryonia 30 and things were fine.. except that I started getting:-

1. Watery running nose - it starts any time. Be it morning, noon, evening or night. Very thin, ropy and watery discharge starts all of a sudden and I have to rush around looking for a paper napkin. When I lay down on bed, the watery discharge rolls down to the back of my throat (it is a little sweet in taste).
Many a times I have to forcefully expel the mucus - it is usually always water like but ropy, but is a little white in color during the morning (right after I wake up)

2. Chain of Sneezes - I am really having very very strong sneezes. Many a times while driving, while laying down on bed just before sleep, some times even during changing sides while sleeping ( I get this sensation that the mucus within the nostrils is also starting to drain out when I change sides) and then a chain of sneezes start. It typically lasts b/w 3-4 times in a row, but some times I sneeze like 10 times straight.
The sneezes are so hard that sometimes my head just misses banging on the car steering or I have to literally bend down and sneeze to avoid getting a cramp in my back!

Very often I also get a tingling sensation in my nostrils and that is followed by either discharge or sneezes.

For the past week or so, I am noticing many a times that my nasal passage is a little blocked and that I have been breathing from mouth.

Some observations that I have had (but I am not certain) is that the sneezing does get triggered when I am in Air Conditioning or somewhere near perfume/deodarant.. but the symptoms are definitely not limited to these circumstances.

I have been taking about 2 pills a day (1 morning and 1 evening) of Arsenicum Iodatum 3X for close to 45 days now with no noticeable relief.

I had symptoms of similar watery nose discharge about 5 years ago, but it got cured with medication ( I really don't remember what the doctor gave me and there was no medical history log to look at).

It has now come to a point that I am afraid if Ars Iodatum may do something wrong since I have been taking it for so long.

Please help.
