Hello again lovely forum peoples

Okay, so it's a new day, and I have a new issue with my PE's reader side. In a nutshell, it takes forever for a page to turn. Actually, it's everything on the reader side. Menu icons, page jumping, page turning, and even writing in the journal has gotten to be a looooong and aggravating time for me. I tried using the on-screen page turning after having pushed the page turning button, and noticed the same loooong page loading time. How long you ask? Too long. Admittedly, I am a pretty fast reader. I devour books. But still, I can push the page turner on a new page before even reading one word, then read the whole page, and still end up waiting over 20 seconds before the next page finally loads. Did this repeatedly to make sure it wasn't just a random occurence. When touching the icons, there is quite a bit of lag before they respond accordingly as well. Some slight lag when writing, but I don't really use the jourrnal too much for it to bother me. Is there anything you, wonderfully brilliant and helpful forum lovelies can think of for me to do to remedy this?
For now, I have downloaded coolreader, and have been using that. I would really much rather prefer to use the eink side. I wear glasses, but find I don't need them when reading an actual book or eink screens. I can read on the LCD side without my glasses as well, but find that it strains my eyes, and gives me headaches after prolonged periods, even when wearing my glasses. I spend hours reading, sometimes not even sleeping, due to recurring periodic bouts of insomnia. So, if any of you can think of something that may help me, I'll probably love you forever. Okay okay, maybe not actually love you, because I don't actually know any of you personally. But I will be really grateful and think long fond thoughts of you as I spend hours of pure reading bliss.
