Optimizing query with having and count

[bw h ontwerpers]

Can anybody help me with optimizing this Query?
I want to get all the item_id's with a variable nr of linked options.

The main table is items, Then there is a second table with filteroptions. The filteroptions are linked to items in a many to many relation by the table filteroptionslinks.

Table structure:

----items----
item_id
....

--filteroptionslinks--
option_id
item_id

--filteroptions--
option_id
...

SELECT fol.item_id
FROM filteroptionslinks fol
INNER JOIN items ON fol.item_id = items.item_id
WHERE items.publish = 'Y'
AND fol.option_id = 112
AND fol.option_id = 115
GROUP BY fol.ITEM_ID
HAVING count(fol.item_id) = 2


Then i need an addition to count the nr of results of this query. Currently i can't do this by saying SELECT COUNT(fol.item_id) because this will just return multiple rows with the value 1.
