Alright ill talk to my doctor about it when i get the results back from the holter monitor testing. Benadryl worked well for me because i could take 2 every 4-6 hrs. But i found i got dizzy since it was working so well at helping my heart slow down combined with my atenolol. Right now my dad told me to get a generic brand of claritin and its not doing much at all for me. Is there any tests i could do to determine if its mast cell related or not? I would really like to get all my medications straight before i leave for england. 😛 haha my purple monkey! He has bunny rabbit ears on him too. Hes a very odd but unique monkey 😛 i saw him and i knew i had to get him 😛
