Nail polish is okay. Fake nails will rip your natural nails off if they catch on anything. Your nails will not be strong enough to take the stress. Don’t know about builder gel. Gaviscon is fine. Make sure you have panadol and also an antihistamine is a good idea as for some people it counteracts the side effects. After the first round of chemo is done and dusted, you will have a good idea what extra drugs to ask your team for. The thing to remember, is that it is doable. You will have bad days but you will also have good days. Get out and enjoy some fresh air but not too much sun. My team recommended fifteen minutes of summer sun per day for vitamin D and my vit D levels were never low. Plus, the fresh air will make you feel better. Keep up your water intake. I found adding ice helped. Frappes were and are my friend. Short walks when you can and when you can’t, snuggle up instead. The time will go fast once it starts.
