For most patients, the effect of Botox starts to kick in between 3 and 7 days. It sounds like this second injection round was being used to attempt to counter the effects of your previous results that you were not happy with.
Each Botox treatment is, or should be, customized to accomodate for the individuals muscle bulk, and their expression lines/wrinkles. Depending on the market where you live, physicians will charge $50 to 100 dollars for consultation. Some consultations are complimentary. This time is important to give you an opportunity to speak with the physician and find out what their injection philosophy is, if they have great listening skills, and if you feel comfortable with them treating you. This is not the kind of information a receptionist can give over the phone.
Ask your friends who are happy with their results, who their injector is and take the time to schedule a consultation with these specific physicians/providers to see if you like their approach.
You may need to wait out the effects of this round of Botox, if you continue to be unhappy with the results as it kicks in. You can then go to a new injector with a "blank canvas" that they can treat conservatively so that you are happy with your results.
