How soon after the surgery did you start going to the gym?

I started going to the gym 10 days after my surgery, however I am worried about putting my body into starvation mode since I am consuming no more than 400 calories a day.  I do about 10 mins of cardionand some strength training for arms etc.  I don't want to go all the way with the work out because I don't want to make myself sick.  When I went to the gym yesterday after my 30 min workout I wanted to do zumba but I started feeling dizzy while standing in line so I left. 
What was your workout regimen like soon after your surgery?

hi! Soooo i was wondering the same thing you were... i had my sleeve 2 days ago on the 22nd and my surgeon said for me to just do SMALL weights like 5 lbs and walking. nothing too crazy! and he said after a month and after my 3 week check up i can do the hard core stuff like running, weight lifting, biking, crunches, all that good stuff.
