Just saw my doc on Thursday and she suggested I take Phen every other day once I have the regimen going. Not sure why.....she said it wears off and the best thing to do is to stretch it out and use it when you need it, but don't rely on it to make you lose weight. Have to do exercise and moderate portions, which are the key to safe weight loss. ????
But even though I have higher than normal blood pressure, she told me it will be ok and it's safe to take for the next few months.
Hope this helps.
