Please use caution when planning to start this supplement. I do not fault this brand at all but Lion's Mane is definitely not for me. I only saw the positive reviews and articles online before finally trying it. Huge Mistake!! I took my first capsule yesterday morning. Last night was the weirdest night of my life. I'm 56, Male, diagnosed with Major Depressive Disorder and Anxiety. I drank alcohol for a very long time in an attempt to self-medicate. I've been sober and in therapy now for 1.5 years. The side effects from last night through today is extremely worrisome. As I lay down to sleep, I had very strange thought patterns and felt like I was floating in and out of consciousness. I had a terrifying nightmare and woke up today feeling nauseous, dizzy, uncoordinated, and I keep hearing drumming sounds every time I move my eyes around. My anxiety is through the roof at this point but I'm scared to take any other medication until this is completely out of my system. Again, I'm not discouraging anyone from trying this brand, it's just the brand I chose. After researching today, there are numerous folks who've experienced similar effects afterwards, some lasting months even after one dose. Oh how I wish that this information was learned before I tried Lion's Mane. I pray that my body, mind, and emotions return to normal ASAP. I see my Therapist and Psychologist tomorrow (IF I'm able to drive!)
