hey im new and was wondering if you can help me also, I have been on phen for a week and have lost 7lbs, but the other day (two days ag0) it was extremeley hot outside (105) and i was outside, so when i got in I couldnt take deep breaths, so i started to panic and google my symptoms and we all know where that leads us to....heart attack. I went to the hospital and my results were all great. I have a good healthy heart. Thank God. Just always have had anxiwety. My last attack was in december of 2011. Anyways I dont want to stop but have been too scared to take the pill the last two days and want to start up 2moro again, for its all that has been working for me. I also am curious. While taking it I was drinking slim fast, could that have triggered something??? I was and will continue only taking half. Please any advice will be grateful. Have u ever had anxiety/ panic attacks and if ya Has ur anxiety attacks gone away?? what will help??? whats the worst side effect you have experienced??? I could tolerate, the headaches and dry mouth..and if I have to the panic attacks also. But am really wondering could it have been my mind over-powering my fear or was it really the only thing that has helped me lose weight in 2 years!?!?!
