Postpartum sweating?

I am 3 weeks postpartum and Im excessively sweating if I do any physical activity, just going for a walk with my son in a t-shirt in 60° weather and my shirt was damp. Not only do I sweat excessively but it makes me smell god awful. I know everyone has BO when the sweat but its never been this bad. My midwives said its my body's way of loosing the babyweight but how long is this suppose to last? Since Im still on maternity leave I like to take any opportunity to get out of the house but this is making it really hard to be comfortable around ppl and its becoming very frustrating. Not to mention I plan on going back to work in 3-4 weeks but Idk how Ill be able to work effectively if Im sweating so bad. Anyone suffer from it this badly?
