Hi,Yes I did have Chemo, waited a couple of months, then went on 150mg of Tarceva, had a lot of diarrhea,perscribed Lomotil, 2 tablets before each meal, no fried or spicey foods. Had some weight loss, so the 2nd year I was on 100 mg tablets and it was much better. I just had a PET & CT scan and will get the results in 2 days. This is routine, am feeling great. I had lung cancer NSCLC & squamous cell in the same lobe. I had lost my hair with the chemo and it was growing back when I went on the Tarceva,the hair is growing very slowly. I did not lose hair with Tarceva. I came off of the drug because this was my plan of treatment from the beginning. Have a very positive mind and you can get thru Tarceva. It is a drug that is very hard on the skin. I got cuts on my fingers by the nails and used liguid bandaid. For my dry body skin I had a perscription of Ammonium Lactate 12%, or used Hydrocortisone 1% at drug store,use Dove or Aveno in the shower, Biotene mouth wash, and I chewed a lot of gum, very dry mouth. I used a natural body cream Honey Meil which I found to be the best. Scented creams don't work. Good luck to you, keep in touch. What is BAC???? You are in my prayers Vette
