    Not what I really expected

    Posted by Reviewer1580503 on Mar 28, 2009

    I normally buy another brand of time release capsules. I really expected capsules, but these are tablets. They seem to be working the same,however, I still prefer the capsule to a tablet.

    This worked for me for a while but now seems to be too strong for me. May just be my system not the product.

    Seemed to cause an upset stomach the first few days I took it, but now everything is back to normal. I don't really feel any different since starting this though.

    Can't review too well because I didn't take it constantly..I like Sam-e 400 more for calming effects. Didn't notice appetite lessening..or maybe it did..sleeping I have no problem anyway so don't know if it helps with that.
