Oh lord.
As a rule Reta is started at 2.5 mg in the research studies. That is what you took. Reta doesn’t really give people “feels.” You need to take the same dose for 4 weeks before increasing your dose. Reta doesn’t really affect food noise for many until they titrate up; instead, it will provide you with early satiety- eat a smaller meal and wait 10-15 minutes before getting more food to see if you feel full.
Reta does not reach full effect in your system for 4 weeks. The danger in increasing your dose too quickly is increased side effects, especially heart rate.
What is your goal with Reta? Are you using Reta to try and cut body fat, or to lose weight overall?
