Stace,
I am taking the phen 37.5... i experenced headaches and was really tired, however i talk to my doctor.... she told me to brake the tablet in half take one in the morning around 7am and the other half around noon.... this really helped.... i also began taking a multivitamin (check you Iron level) and Girl let me tell you it did wonders!!!!
and when working out dont over work yourself.... make sure you are still eating enough caloires to support your body..... I am a house wife with 3 little boys (ages 7,5, and 2)... so you could guess how tired i am by the end of the day!!! but now with the changes i have made are working out great for me.....
hope things work out for you!!
