What's the longest you took Phentermine before you developed a TOLERANCE?

I've been reading a lot about phentermine TOLERANCE and wondering if some of you could share your experiences . Thanks!

Lots of viewers, no responses.

Anybody got some input?

The first time I took Phentermine back in August 2006, it took me about 2 1/2 months to feel like I was building a tolerance. I continued to take it, and still lost slowly until Jan 2007, then took another break and restarted 3 wks later until March 2007.

I started again May 1, 2007 and noticed it starting to build a tolerance again around the week of July 10th. My pcp switched me to Phen-D which I had major problems with the first day.

Tues I am starting Phen/Adipex back so I'll let you know if its about the same time frame.

I well remember taking it every day for 10 weeks and it seemed to build in effectiveness the whole time! My prescription ran out so I never got to experience tolerance.
I added 5-HTP and B-12 at my doctor's suggestion but did not feel any appreciable difference. I STILL had to work at food rationing. Losing wasn't easy but the medicine gave me the boost I needed to get the job FINALLY done!
And my friends here on PhenForum kept me honest!

Tolerance smolerance, I wish they'd put it in the water like fluoride.

Hey Lisa- what's Phen-D?

Thanks for the feedback. Once again, it sounds like it may vary with the individual. But there does seem to be some consistency in reports about 10 weeks or 2 1/2 mos.

i've been taking phen for 3 and a half months & its still working for me. i think i have noticed that in the evening i have started to feel a bit more hungry but in a way i think it is a good thing because i am having to use my personal will power & that has increased GREATLY since i have been on phen.
good luck.
everyone's body is diffrent so it will effect everyone diffrently
