What would you tell yourself on day 1 of reta if you could ?

Long story short these past couple weeks i have started watching my calories and protein, i’ve been doing 2400 calories and 180-200g of protein. And also gym 3x a week and 7500 steps a day (i plan to up it next week to 10pm and eventually end up at 20k)

I ordered Reta yesterday 10MG and am looking for any tips you guys could offer.

My goal is to start at lowest risk of side effects and slowly move up.

I was assuming maybe i should start at .5mg and after a couple weeks move up to 1 and then so on and so on.

I’ve seen you need to drink a good amount of electrolytes and stuff, basic things but what else should i be taking ? What side effects should i expect etc ? Any advice is appreciated

I am 31, 5’9 and 287 lbs.
