I would like to know if there are any studies regarding the combined effect of cigarette smoking and phentermine. I am curious because the last time I tried phentermine I was a smoker and I felt very “speedy” and restless on it. I have recently started taking it again and I am now a non-smoker. My experience with it so far is much more pleasant than I remember. I am not sure if this is because I started out taking a half dose for the first few days, or if it is because I no longer smoke.
I would appreciate any information, scientific or anecdotal, anyone may have about this. Thanks!
