How long will breast aug symmastia reconstruction recovery take? (photo)

Wow! I admire the optimism and positive attitude. 
August 11th will give you about one month into your recovery. Although you can probably drive, I would advise you not to do any heavy lifting until about 6 weeks after your surgery. Please have this discussion with your surgeon.  Synmastia repair is a tricky surgery and you need to diligently follow instructions to insure a good outcome. 
Now, looking at your photos, I have a few things to consider that might make your appearance better and help the synmastia repair. First, I think one of your options is to do the repair and consider using smaller implants. By decreasing the volume, you will put less pressure on the synmastia repair. If you decrease the volume, you could also consider a procedure to raise the implants and prevent them from falling and causing "bottoming out". I think you have two options to help the bottoming out. A capsulorraphy is an internal procedure that lifts the breasts without any extra scars. You might be able to achieve more upper breast fullness with this technique. If you stay with the same size, you can also consider using a mesh or "matrix" to support the implants. I bring these points up since you are already going to be under anesthesia for the synmastia repair. Have a discussion with your surgeon to see if he thinks these procedures might be beneficial for you.
So again, I think you can drive, but I think lifting heavy things is not a good idea until 6 weeks after surgery. Have a discussion with your surgeon and follow his instructions to insure a successful outcome.
Good luck.

I am sorry to hear about your concerns after breast surgery.  In my opinion, you will benefit from correctional medial breast implant position as well as from correctional "bottoming out" of breast implants.    Keep in mind, that these types of revisionary breast operations to require significant experience when it comes to achieving successful outcomes.  
In my practice, having used a variety of “techniques” for correction of symmastia, I find that the most reliable technique involves a 2 layer capsulorrhaphy (internal suture repair of the breast implant pockets along the cleavage area). Often, the use of acellular dermal matrix is helpful also. I have also been pleased with the (at least partial) correction of skin tenting that can be achieved with the use of the acellular dermal matrix.
 I also find that careful attention to postoperative activity restrictions is key to success with this type of surgery and other types of implant malposition revisionary breast surgery.  Activity restrictions are individualized patient by patient, depending on exactly what was found and done during the procedure.  For example, for most of my symmastia  patients, I ask that they avoid pec major related exercises ( especially exercises that involve abduction of their arms) for at least three months after the procedure is performed.
My best advice: select your plastic surgeon carefully. Make sure that he/she has significant experience achieving the types of outcomes you will be pleased with. Then, communicate your goals carefully. Working together you will come up with a good plan to achieve your goals.  He/she will review necessary postoperative restrictions with you.
 Best wishes for an outcome that you will be very pleased with.  

There are different options for repair of symmastia but with large implants it will likely involve reinforcement with mesh (GalaFLEX) or ADM (Strattice.) The implant diameter is a concern also. A month is usually OK for recovery but you will get the best advice from your own surgeon.
