Please read below and help...I don't know what else to do for this poor fish. Every morning he seems fine and is swimming around lively, then by late afternoon/early evening I am having to tap on the tank to make sure he's even still alive. My plan when I put him back in the Epsom 4 days ago was to fast him for 5 days. He pooped on Day 2 but hasn't pooped since and to be honest I'm not sure he has anything left in him to void, I am more hoping that the fasting will give his insides a break but he just doesn't seem to be improving. Has anyone ever seen anything like this? What else can I do for him??? Thanks in advance!

Symptoms and Treatment
How has your betta fish's appearance changed? Most of the time his appearance is normal but he sometimes develops a "kink" in his body so that he looks curved or s-shaped
How has your betta fish's behavior changed? Each morning, his behavior is completely normal. By late afternoon or early evening he starts to look like he has a bad case of SBD - he is overly buoyant and can't stay down from the surface, he tips over onto his side, and he sometimes struggles to swim. Then by morning he is acting normal again.
When did you start noticing the symptoms? About 3-4 weeks ago.
Have you started treating your fish? If so, how? Yes. I did Epsom 1 tsp/G initially for about a week, then was advised here to increase to 3 tsp/G, which I did for 14 days. In the midst of this, he jumped out of the cup while I was changing the water and spent about 20 second flailing around on the kitchen counter but seemed to recover ok from that. At the end of the 14 days, he seemed to be doing better so I tapered down the Epsom over the course of 3-4 more days and then acclimated him to his home tank with no Epsom and within hours he got worse again. He has now been back in 3 tsp/G Epsom and fasting for the past 4 days.
Does your fish have any history of being ill? He had a prior episode of SBD in mid-October that resolved after 10 days in 1 tsp/G epsom and fasting.
How old is your fish (approximately)? Not sure, I got him about 6 months ago.
