hi, im on day 14, four pound loss so far (don't weigh till thursday of this upcoming week) but wanted to know...the past three days i've had headaches. I naturally try to defend that its not the phen, could it be that i've just about given up ALL caffine as far as NO sodas and/coffee for the past two weeks on phen and BARELY and i do mean half a glass if that as a treat of diet soda (to keep away from sodium as a reason to retain water)?
OR.....are headaches pretty common on side effects for phen?

Headache is a common Phentermine side effect, and you're right about the
caffeine withdrawal. That can cause terrible headaches too.

I also read on the Phen.com forums about a woman who has her period
three times every month since she's using Phentermine. Lol that's terribly
inconvenient. For other people, it's just been once a month but lasts longer.

Yes, I have had headaches too. But not severe ones. Are your headaches terrible? Are you taking anything to relieve them?

I've been on phen for 7 days. I had a headache the first 3 days, then it went away and i haven't had one since.
