I started on Thursday also. Lost 4 pounds since then, but I can't say whether it was because of the Patentlean. But I'm going to keep taking it for awhile just in case!
I haven't noticed any side effects at all - have you guys? Can't believe how tiny the pills are. Every diet pill or supplement I've ever taken before has been huge pills! These are much easier to swallow.
I noticed somewhere in the paperwork that came with it (or maybe it was on the bottle, I can't remember) that they suggest giving it 8 weeks to see results. Don't know if I'll try it that long or not - it depends on whether I reach my goal before then.
We'll have to post about this again in awhile & compare our results, since we all started nearly the same day. Good luck!
