Brazilian Butt Lift (square shaped gal)-Beverly Hills, CA

Just had my consultation last week and I am soooo excited! I have lived life as an apple shape and hate it!!! I'm 5'2 currently 155 lbs and 20 yrs old. I have been wanting this procedure for the past year so I gained approx 20 lbs just for this and I plan on gaining 10 lbs more just to make sure I am happy with the result! ( I'd rather it look a little bigger than I want rather than smaller) I will have lipo from flanks, lower back, entire waist&bra roll and abdomen, I'm hoping to ask the DR if he can lipo my upper/inner thighs for that sexy "gap" look. after the procedure I'm planning on hitting the gym as hard as I always have before gaining weight for this... I just want the best results possible!!! I'm so excited, only 2 1/3 months left. Any advice on healing process or precautions before I do surgery? Btw has anyone medicated themselves with painkillers along side medical marijuana products such as edibles or thc pills!?

I guess dr Matlock has some type of conference the day of my SX Monday jan 13 -__- luckily they have moved it to just a few days later on Thursday Jan 16... I'm a bit nervous since I start school the first week of Feb which means I'll have a total of 3 weeks recovery before having to sit for 10+ hours a day in lecture. Will a boppy pillow work well or the yoga may under thighs trick work better. I don't want to lose any volume due to school... Please help!

Made some wish pix with an app... Note I did NOT enhance my buttocks just contorted my waist and contorted my thigh (just a pinch) on the side view pic.
