Unintentional chronic regurgitation heart burn

I am suffering from regurgitation ever since I can remember. I thought it was normal till I was told otherwise by a doctor friend. I was suggested some tests, but I prefer a non intrusive diagnostic and prefer homeopathy.
Symptoms:
I regurgitate almost after every meal.
Sometimes it's acidic sometimes it is not (sour in taste)
It is more prominent after heavy meals
I find it difficult to sleep on my right, it increase many folds
I have a chronic vitamin b deficiency with all symptoms associated to it (forgetfulness, broken lip corners etc)if it is digestion related
I take b complex supplement regularly
Please let me know if more information is needed.

Thanks a lot in advance.. :-)
