Skeptical.....but... it actually works! I read the reviews on Amazon, Walmart and Walgreens and very high ratings. But, still, I was like yeah but I have a serious medical condition, they probably won't help. I also over load my brain with work and school and that's my problem. Nope. Day 2. Yea only day 2 of taking them and I found myself thinking clearly and comprehension was better. Overall mental clarity was better. Not great. But better! The taste is not great. I can chew it and drink something after. The taste is less than desirable. But considering it works, I'll take the taste and be happy with results. Highly recommended.
