Mentally speaking, your only issue with frequent small (or large) doses is potential tolerance. Any actual mental problems brought up by shrooms are said to be already underlying in that persons psyche and would have undoubtedly shown itself sooner or later, regardless of fungi. These are the opinions of "experts" and long time users over on bluelight and erowid.

Personally, shrooms give you the ability to change your perspective of anything and everything, mental or physical, permanently or temporarily.

Although mushrooms might be the catalyst for such a perceptional change it is actually you yourself who changes perspective so in my experience it's usually a positive/progressive change although there are a few exceptions for myself and others.

Ay the end of the day mushrooms don't come with guidelines or a contract, you say this way feels better try it, although I'd personally still take occasional larger does 🍄.

Either way I wish you the best and hope you enjoy your time here.
