Not on protocol
if you abruptly stop the injections & don't follow the protocol for the maintenance phase, you WILL gain the weight back.
The 3 weeks following the injections are just as important as Phase 2. There are ways to deal with interruptions while on the plan, but they are very specific. Your Dr. should discuss this in detail with you . You can read "Pounds & Inches" by Simeons for more info.
