Just make sure you don't try to go too low on your calories without the HCG. You could continue on HCG and just try going rogue and adding in enough healthy carbs like fruits and maybe whole grain breads to keep you out of ketosis. Since you have to quit it's worth trying it another way before you do. I just started a general low cal yesterday with HCG to see how it will work. No ketosis, no super low cal, just a range that worked previously for me 700-1100. Too soon to tell how well it will work long term but first day went well.
