Welcome to healthcare Magic!
My first and foremost suggestion is that you should not do anything of that much importance without knowledge of your parents.
Respect their trust in you.
Synedrex is a blend of some sympathetic drive, increasing drugs and three B-complex vitamins
, It helps in reducing the weight by increasing the basal metabolic energy expenditure and more activity levels. It also causes a boost in mood.
But all that glitters is not gold. it can lead to rapid heart rate
, surge in BP, lack of sleep, impaired memory and errors of judgement in driving and operating machinery.
You have poor tolerance for the drug so should avoid it or if at all start it at lower doses and build up slowly as your tolerance improves.
Take care not to stretch too much under the effect of the drug because it will lead to tired state when the drug levels are low.
I hope the advise would be informative and useful for you.
