I stopped taking it for three weeks after like 2-3 months. I mean, I guess I can go without it again. I didn't add much weight during that time. Maybe I did; hard to tell. BMI went up maybe one point? But I mean, it's so cheap and my rhr difference isn't noticeable while on it.
My RHR could actually be lower on reta because I tend to stop eating earlier in the day and sleep inadvertently ends up being better. So I'm like, I guess I'll continue taking it to stay eating healthy for a while until the habits lock in. Dunno. Or just stay on it, go off and on. Hard to say. For now I just feel better while taking it because I eat better while on it.
I don't think there's anything wrong with taking it. You shouldn't feel "bad" for taking it to feel better, fix your diet, or whatever else.
