Former WWE star Sunny has checked into a retreat center ... this according to her sister, who claims Tammy Sytch has done so in an effort to "get healthy again."

Tammy's sister tells Pro Wrestling Sheet ... "her health has not been good lately and she is at a retreat to try and get healthy again."

She adds, "It's a retreat that focuses on the body and mind while using a holistic approach offering yoga, music therapy, art and holistic supplements to help the body heal. She is hoping to feel better soon and looks forward to a healthier future."

In case you missed it, the ex-wrestling manager released a sex tape with Vivid this year and wore her WWE Hall of Fame ring in the video.  The 43 year-old was hospitalized not long after, but remained active on Twitter until the end of last month when she suddenly went silent.

UPDATE: 10:30 AM PST - TMZ confirmed our report and in addition claim that sources tell them Sunny reached out to friends last month, informing them she was seeking treatment to get sober.

The site also says Tammy told friends she was hopeful her stint in rehab would "offset" possible jail time in her DUI cases.
