I'm sorry about the diagnoses but at least now you can start treatment and hopefully feel better soon! I started placquenil just over 3 months ago. I started on 200mg a day for one month than increased to 400mg a day. The first 2-3 days on it and when they increased it, I felt funny. It didn't really effect tummy too much, it just made me jittery and I couldn't concentrate and I just felt wrong! It wasn't too bad and only lasted a couple of days.
The eye test they are going to do is a dozy though! Bring sunglasses because you will be dilated and your vision will be blurry and light sensitive for a few hours. They will also do a visual field test in a big machine with red lights, this caused a reaction in me and I passed out, thats not the norm though!! There is a certain ratio they use, so many milligrams of placuqneil for your weight. As long as they keep it under this particular ratio, which I can't remember this second, its very unlikely to damage your eyes but you will need thorough eye exams once a year.
I hope you start feeling better soon! Hugs!
