Hi Venkat,

Hope you are doing fine and it is unfortunate that you have to be here but this place is weath of information and will lead you to the road of recovery.

For #1: Therabite is expensive so I hope you have read the feedback. Honestly speaking, some regular excercise will help you more.

For #2: Post-radiotherapy, it takes almost an year for saliva to thin out and develop taste-buds. Considering you are from AP, you may not be able to tolerate acidic and spicy stuff for a very long time. Once RT is over, you can probably try Papaya (Juice) to thin out saliva.

For #3: Yes the ulceration will go away, drink lot of water (atleast 4-6 L a day). If it is troubling you, you can try aloclair gel.

You need to regain weight, if you are veggie then it is going to be problem.

Take care and hope to hear from you soon.
