Good you have something to strive towards ???? and if hes said that he sounds like he is really trying bless him. After 7 days he will bs a bit more clear headed. Reality is though its 10 weeks. Week 1 to 10 he will experience lack of sleep, vivid dreams, mood swings etc…
When he starts night sweats it means his liver functionality will be returning to normal this is common. He just has to ride it out. And routine is key especially what time to go bed and get up.
I was up till 4 am yesterday morning but I made sure I was out of bed at 7.30 hence why I slept last night.
Any questions at all am here
