LPR(Laryngopharyngeal Reflux) + IBS , pls help

I am 20 yr old, male.

I have two main problems - IBS(from past two years) and LPR(from past one year).

My symptoms are as follows-

LPR - feeling of mucus in throat especially at early morning and night along with pain, frequent need to clear the throat, sore throat, pain aggravates on speaking for long time, feeling of acid reflux accompanied rarely by heartburns, abdominal constrictions on both sides below the ribs

IBS - anxiety, very loose stools, flatulence , inflammation feeling in rectum after passing stool, mild irritation in anal region especially on the day when very loose stool is passed, sometimes abdominal cramps in the morning, however no frequent urge to go to toilet

Other symptoms includes headache(almost everyday), feeling sleepy all day, very uncomfortable sleep at night due to dreams, feeling very tired on waking up in morning.

I did a bit of research on homeo remedies for my problem and found some very appropriate for my symptoms-

IBS - Nux Vomica
Anxiety - Arsenicum Album/Kali Phos
Other symptoms - Alfalfa Tonic

I have earlier taken Nux Vomica(30c and 200c) many times for my IBS problems but the problem is that it gives relief till I am taking the medicine and the symptoms come back on stopping the doses.
I have also taken Kali Phos 6x bio-chemic pellets for about 15 days about 6 months ago but it didn't gave any releif.

Please advice me remedies for both of my problems - LPR & IBS.
