I have had Covid twice since 2020. The sweating is just as you said, and unless you have experienced it no one really understands how debilitating it can be. You are loosing body fluids and could easily become dehydrated unless you’re drinking enough water to replenish these fluids. I’m had one vaccine and had an allergic reaction so I’m pretty sure it’s not from the Covid shots but from Covid itself. Long Covid is probably the cause. I don’t wear too many clothes anymore because it creates laundry and excessive work. Robes to fit your climate are a good idea if you can do that. I’m retired RN and my kids are grown so it’s a bit easier for me. This is a bad side effect of Covid. I’m sorry you have to deal with this.
