Many symptoms..is this bad?

[Bellydancer21]

I started taking Phentermine exactly one week ago..since then I have had many symptoms: headaches, dry mouth, constipation, tense all over. I want to continue taking the pill, but not sure if these symptoms will continue. I have had sucess so far with weight loss.. 8lbs in a week! I'm eating good and drinking lots of water (mostly due to dry mouth, I guess thats a good thing). I try to exercise as much as possible and I am also getting B-12 shots once a week. Has anyone had all or any of these symptoms..and if so any suggestions??

I have taken phen for about 5 weeks now and am having daily headaches. I even went to the eye doctor to have him make sure nothing was seriously wrong with my eyes! As I am writing this I again have my daily headache, mostly around my eyes.
Not sure what to do. I have lost 12 pounds which is something I have never accomplished before. Anyone have any suggestions as to when these headaches will go away or what I can do short of coming of the phen?

tHE HEADACHES ARE normally caused by not drinkiing enough water...when i was on phen i had a headache like everyday then after about ten days or so they went away.....drinkiing lots of water will for sure help with the headaches tho.....also make sure ur eating enough calories a day.......The dry mouth is also normal.....its a commone effect with phen.....constipation is another common effect so make sure u eat enough fiber in ur diet or take a stool softner a day cause it is no fun beng constipated.....but yea all ur effects are so normal so just hang in there and give ur body time to adjust to the phen....and good luck with ur weight losss......
