I am taking Biotin, ProbioMed 100, Lion's Mane, GI Revive and Pau D'Arco starting this am. I noticed a blister on top of my mouth. At 9:00pm I suddenly got a severe headache, radiating through my neck and eye. Help?

Try the GI Revive after two days. IF you feel fine you may try 1 Lion's Mane again. IF you react, leave it out. THRILLED for you with all the wonderful progress you have made. Congratulations on making this commitment to yourself!
