have others had strong side effects from sublingual heparin? if you could share you experience with me i'd appreciate it. i began taking .5cc sublingually twice a day one month ago and have never been so fatigued in my life. my neck and shoulders ache, i can barely drag myself through the day and can't concentrate. it is strange because my symptoms pre-heparin were mostly muscle pain-related, not fatigue. i do have a "chronic/reactivated" EBV test result though. also, if i take just 1/2 capsule of transfer factor 4000 i feel about 10 times more awful. how long does it take to get over these effects with heparin and transfer factor?
