Hi,
Yes, you should be fine. I’m now on session 17 of 20 and have a journey time of between one hour and a hour and a half. The wife drives which can be quite stressful (she drives different to me eg in situations where I would brake she accelerates 😅). I was a bit worried to start with but it isn’t really a problem. Just follow the instructions, a bottle of water isn’t actually that much, just have a pee straight after the radiation and you’ll get home ok.
The biggest worry I had one day was when I had to travel in for a 7:30am start after I’d been up all night with radiotherapy induced trots (I’ve had these twice now, they are not pleasant 🤢). Thankfully, we made it without any drama but it was a bit of a nightmare. I’ve definitely got a side effect impact on the bowels currently stopping me going for long walks.
I’m sure you will be fine, remember to take a book with you - good luck.
