Has anyone taken LDN along with a heart med? I tried about 3 doses of LDN, 0.5mg in March. I took it at night and was tired most of the next day. I was worse. I am considering trying it again. I was diagnosed with a new heart issue (VT) in May and tried a beta blocker at night for two months. I was feeling a little better before starting the heart med. I was tired all day again while taking the beta blocker. Switching to Diltiazem now. Assuming I should wait a bit (any idea how long?) to see how I do with this med but would like to try the LDN again as soon as possible. Any thoughts much appreciated.
