Well I did a little amature detective work and found that during my heart palps my pulse rate is 100-110 BPM normal blood pressure (120/75). During the times I feel dizzy/weak/faint my BP is about 90/60 with a pulse rate of 54 or 55. I contacted my doctor with all my info and she told me to take Sudafed, Drink 2 or 3 caffine drinks a day and drink TONS of water. I already drink tons of fluid in order to keep my milk supply going for my baby. I already drink 2 caffine drinks a day. Sudafed makes me feel wierd. I am sorta dissapointed but the symptoms scared me so I guess it was good that I brought it up. Guess I will throw in and extra caffine drink and try some Sudafed.
