Hi, since May Ive experienced what seems to me to be long-Covid like symptoms as a consequence of taking the AZ vaccine. I have read that there has been some improvement to LC by taking antihistamines and would be willing to try if there werent any major dangers to doing this for someone with M.E. I did try Loratadine a year ago (an M.E doctor recommended) and after taking 1 they made me extrememely drowsy and i didnt try any others for fear they might be doing me harm. I bought some Benadryl (so am ready to go), but before I try it I thought i'd better post to see if there was anything I should know... is there?
